By default, omap_devices will be automatically idled on suspend

In the omap_device PM domain callbacks, use omap_device idle/enable to
automatically manage device idle states during system suspend/resume.
If an omap_device has not already been runtime suspended, the
->suspend_noirq() method of the PM domain will use omap_device_idle()
to idle the HW after calling the driver's ->runtime_suspend()
callback. Similarily, upon resume, if the device was suspended during
->suspend_noirq(), the ->resume_noirq() method of the PM domain will
use omap_device_enable() to enable the HW and then call the driver's
->runtime_resume() callback.
If a device has already been runtime suspended, the noirq methods of
the PM domain leave the device runtime suspended by default.
However, if a driver needs to runtime resume a device during suspend
(for example, to change its wakeup settings), it may do so using
pm_runtime_get* in it's ->suspend() callback.

Add a new field to provide the mode supported by the module.
The mode will control the way mandatory clocks are managed by the PRCM.
0 : Module is temporarily disabled by SW. OCP access to module are stalled.
Can be used to change timing parameter of GPMC module.
1 : Module is managed automatically by HW according to clock domain
transition. A clock domain sleep transition put module into idle.
A wakeup domain transition put it back into function.
If CLKTRCTRL=3, any OCP access to module is always granted.
Module clocks may be gated according to the clock domain state.
2 : Module is explicitly enabled. Interface clock (if not used for
functions) may be gated according to the clock domain state.
Functional clocks are guarantied to stay present. As long as
in this configuration, power domain sleep transition cannot happen.
Some modules will have a modulemode initialized at 1 (HWCTRL) by default.
This is the case for interconnect and simple module like GPIO, WDT, MAILBOX.

In OMAP PRCM terminology, the clock domain is defined as a group of IPs
that share some clocks and most of the time an interface clock.
Every IP does belong to a clockdomain.
For the moment the clock domain attribute is affected to a clock node.
The issue with that approach, is that a clock might or not belong to a
clock domain. Moreover during module transition, it is up to a module
to handle properly the clock domain state and not to a clock node.
Create a clkdm_name attribute to provide this information per hwmod.
Populate this attribute for every OMAP4 hwmod entries.
Future cleanup series with remove that information from the OMAP4 clock
when it is relevant.

The sequence of _ocp_softreset doesn't work for i2c. The i2c module has a
special sequence to reset the module. The sequence is
- Disable the I2C.
- Write to SOFTRESET bit.
- Enable the I2C.
- Poll on the RESETDONE bit.
The sequence is implemented as a function and the i2c_class is updated with
the correct 'reset' pointer. omap_hwmod_softreset function is implemented
which triggers the softreset by writing into sysconfig register. On following
this sequence, i2c module resets properly and timeouts are not seen.

As part of removing cpu_...() from the OMAP I2C driver, we need to
convert the CPU tests into functionality flags that are set by
hwmod class in the same way the IP revision is.
More flags are needed than will fit in the existing u8 flags
member of omap_i2c_dev_attr.
These flags can refer to options inside the IP block but they are
most needed for information about cpu implementation specific
options that are not part of the IP block itself. For example,
how the CPU data bus is wired to the IP block databus differs
between OMAP cpus and affects how you must shift the address in
the IP block, but is not a feature of the IP block itself.

To be able to relocate the .bss section at run time independently from
the rest of the code, we must make sure that no GOTOFF relocations are
used with .bss symbols. This usually means that no global variables can
be marked static unless they're also const.
Let's remove the static qualifier from current offenders, or turn them
into const variables when possible. Next commit will ensure the build
fails if one of those is reintroduced due to otherwise enforced coding
standards for the kernel.

Header files in arch/arm/*/include/mach included from
arch/arm/include/asm/*.h are there to provide necessary definitions for
either the rest of the kernel or the ARM specific parts. They shouldn't
be polluted with *any* platform private stuff which is not absolutely
necessary to satisfy the rest of the kernel.
Hence move the OMAP specific SMP boot functions to different header
instead of keeping them in 'plat/smp.h' which gets included indirectly
by linux/smp.h
The patch is outcome of the discussion in below thread:

NOTE!
This merge commit was created to fix compilation error. The block
tree was merged upstream and removed the 'elv_queue_empty()'
function which the new 'mtdswap' driver is using. So a simple
merge of the mtd tree with upstream does not compile. And the
mtd tree has already be published, so re-basing it is not an option.
To fix this unfortunate situation, I had to merge upstream into the
mtd-2.6.git tree without committing, put the fixup patch on top of
this, and then commit this. The result is that we do not have commits
which do not compile.
In other words, this merge commit "merges" 3 things: the MTD tree, the
upstream tree, and the fixup patch.

Currently IOVMM driver sets IOVMF_DA_FIXED/IOVMF_DA_ANON flags according
to input 'da' address when mapping memory:
da == 0: IOVMF_DA_ANON
da != 0: IOVMF_DA_FIXED
It prevents IOMMU to map first page with fixed 'da'. To avoid such
issue, IOVMM will not automatically set IOVMF_DA_FIXED. It should now
come from the user throught 'flags' parameter when mapping memory.
As IOVMF_DA_ANON and IOVMF_DA_FIXED are mutually exclusive, IOVMF_DA_ANON
can be removed. The driver will now check internally if IOVMF_DA_FIXED
is set or not.

Currently, the n8x0 is the only OMAP2420 platform supported

obtained from the hwmod database by the mcbsp driver. Since DMA programming is
handled by the client driver, APIs are provided to pass the DMA channel number
and base address of data register required by the client driver for DMA
programming.

Hwmod needs database of all IPs in a system. This patch generates the hwmod
database for Display Sub System applicable for OMAP3430 and

For all the IP modules in DSS, same clock is needed for enabling. Hwmod sees
DSS IPs as independent IPs, so same clock has to be repeated for .main_clk in
each IP.
This patch defines separate hwmod databases for OMAP3430ES1 and (OMAP3430ES2 and
OMAP36xx) as OMAP3430ES1 does not have IDLEST bit to poll on for dss IP, and also
the firewall regions are different between 3430es1 and later.

Allow OMAP4 ES2.1 and ES2.2 revisions to be recognized in the
omap4_check_revision() function.
Mainly, ES2.1 has fixes that allow LPDDR to be used at 100% OPP (400MHz).
ES2.2 additionally has a couple of power management fixes (to reduce
leakage), an I2C1 SDA line state fix, and a floating point write
corruption fix (cortex erratum).
Even though the current mainline support doesn't need to distinguish
between ES2.X versions, it's still useful to know the correct silicon
rev when issues are reported. Moreover, these id checks can be used by
power management code that selects suitable OPPs considering the
memory speed limitation on ES2.0.

Cleans up all base address definitions for omap_mcspi
and adapts the device registration and driver to hwmod framework.
Changes involves:
1) Removing all base address macro defines.
2) Using omap-device layer to register device and utilizing data from
hwmod data file for base address, dma channel number, Irq_number,
device attribute(number of chipselect).
3) Appending base address with pdata reg_offset for omap4 boards.
For omap4 all regs used in driver deviate with reg_offset_macros
defined with an value of 0x100. So pass this offset through pdata
and append the same to base address retrieved from hwmod data file
and we are not mapping *_HL_* regs which are not used in driver.

uses this channel parameter to set the correct manager to the corresponding omap_dss_device.
The channel parameter is used only once to ensure the correct managers are set for each
panel. The parameter dssdev->manager->id will take care of ensuring that the panel and
then the interface driver configures the correct DISPC channel.
Also, add a new Overlay Manager in manager.c, make other changes needed for LCD2 channel.

On OMAP4, we have a new DISPC channel for Overlay Manager LCD2. There is a set
of regsiters for LCD2 channel similar to the existing LCD channel, like
DISPC_CONTROL2, DISPC_DIVISOR2, DISPC_CONFIG2 and so on.
Introduce new enum members for LCD2 Channel and corresponding Overlay Manager
in display.h.
Represent the following DISPC register defines with channel as a parameter
to differentiate between LCD and LCD2 registers (and also DIGIT in some cases):
DISPC_DEFAULT_COLOR, DISPC_TRANS_COLOR, DISPC_TIMING_H, DISPC_TIMING_V,
DISPC_POL_FREQ, DISPC_DIVISOR, DISPC_SIZE_LCD, DISPC_DATA_CYCLEk,
DISPC_CPR_COEF_R, DISPC_CPR_COEF_G and DISPC_CPR_COEF_B
This parametrization helps in reducing the number of register defines for DISPC.
Replace the existing reads/writes to these registers in this new way.

There are differnet classes of smartreflex implementation.
Class-0: Manufacturing Test Calibration
Class-1: Boot-Time Software Calibration
Class-2: Continuous Software Calibration
Class-3: Continuous Hardware Calibration
Class-4: Fully Integrated Power Management
OMAP3 has two smartreflex modules one associated with VDD MPU and the
other associated with VDD CORE.
This patch adds support for smartreflex driver. The driver is designed
for Class-1 , Class-2 and Class-3 support and is a platform driver.
Smartreflex driver can be enabled through a Kconfig option
"SmartReflex support" under "System type"->"TI OMAP implementations" menu.
Smartreflex autocompensation feature can be enabled runtime through
a debug fs option.
To enable smartreflex autocompensation feature
echo 1 > /debug/voltage/vdd_<X>/smartreflex/autocomp
To disable smartreflex autocompensation feature
echo 0 > /debug/voltage/vdd_<X>/smartreflex/autocomp
where X can be mpu, core , iva etc.

This patch adds voltage driver support for OMAP3. The driver
allows configuring the voltage controller and voltage
processors during init and exports APIs to enable/disable
voltage processors, scale voltage and reset voltage.
The driver maintains the global voltage table on a per
VDD basis which contains the various voltages supported by the
VDD along with per voltage dependent data like smartreflex
efuse offset, errminlimit and voltage processor errorgain.
The driver also allows the voltage parameters dependent on the
PMIC to be passed from the PMIC file through an API.
The driver allows scaling of VDD voltages either through
"vc bypass method" or through "vp forceupdate method" the
choice being configurable through the board file.

Implement OMAP PM layer omap_pm_get_dev_context_loss_count() API by
creating similar APIs at the omap_device and omap_hwmod levels. The
omap_hwmod level call is the layer with access to the powerdomain
core, so it is the place where the powerdomain is queried to get the
context loss count.
The new APIs return an unsigned value that can wrap as the
context-loss count grows. However, the wrapping is not important as
the role of this function is to determine context loss by checking for
any difference in subsequent calls to this function.
Note that these APIs at each level can return zero when no context
loss is detected, or on errors. This is to avoid returning error
codes which could potentially be mistaken for large context loss
counters.
NOTE: only works for devices which have been converted to use
omap_device/omap_hwmod.
Longer term, we could possibly remove this API from the OMAP PM layer,
and instead directly use the omap_device level API.

J-Type DPLLs have additional configuration parameters that need to
be programmed when setting the multipler and divider for the DPLL.
These parameters being the sigma delta divider (SD_DIV) for the DPLL
and the digital controlled oscillator (DCO) to be used by the DPLL.
The current code is implemented specifically to configure the
OMAP3630 PER J-Type DPLL. The OMAP4430 USB DPLL is also a J-Type DPLL
and so this code needs to be updated to work for both OMAP3 and OMAP4
devices and any other future devices that have J-TYPE DPLLs.
For the OMAP3630 PER DPLL both the SD_DIV and DCO paramenters are
used but for the OMAP4430 USB DPLL only the SD_DIV field is used.
The current implementation will only program the SD_DIV and DCO
fields if the DPLL has both and hence this does not work for
OMAP4430.
In order to make the code more generic add two new fields to the
dpll_data structure for the SD_DIV field and DCO field bit-masks
and only program these fields if the masks are defined for a specific
DPLL. This simplifies the code and allows us to remove the flag
DPLL_NO_DCO_SEL.

Clarify the usage of the struct omap_clk.cpu flags (e.g., CK_*) to use
bits only for individual SoC variants (e.g., CK_3430ES1, CK_3505,
etc.). Superset flags, such as CK_3XXX or CK_AM35XX, are now defined
as disjunctions of individual SoC variant flags. This simplifies the
definition and use of these flags. struct omap_clk record definitions
can now simply specify the bitmask of actual SoCs that the records are
valid for. The clock init code can simply set a single CPU type mask
bit for the SoC that is currently in use, and test against that,
rather than needing to set some combination of flags.
Similarly, clarify the use of struct clksel_rate.flags. The bit
allocated for RATE_IN_3XXX has been reassigned, and RATE_IN_3XXX has
been defined as a disjunction of the 34xx and 36xx rate flags. The
advantages are the same as the above.
Clarify the usage of struct omap_clk.cpu flags such as CK_34XX to only
apply to the SoCs that they name, e.g., OMAP34xx chips. The previous
practice caused significantly different SoCs, such as OMAP36xx, to be
included in CK_34XX. In my opinion, this is much more intuitive.
Similarly, clarify the use of struct clksel_rate.flags, such that
RATE_IN_3430ES2PLUS now only applies to 34xx chips with ES level >= 2
- it does not apply to OMAP36xx.
...
At some point, it probably makes sense to collapse the CK_* and
RATE_IN_* flags together into a single bitfield, and possibly use the
existing CHIP_IS_OMAP* flags for platform detection.
...
This all seems to work fine on OMAP34xx and OMAP36xx Beagle. Not sure
if it works on Sitara or the TI816X, unfortunately I don't have any
here to test with.

Move the padconf save code from pm34xx.c to the System Control Module
code in mach-omap2/control.c. This is part of the general push to
move direct register access from middle-layer core code to low-level
core code, so the middle-layer code can be abstracted to work on
multiple platforms and cleaned up.
In the medium-to-long term, this code should be called by the mux
layer code, not the PM idle code. This is because, according to the
TRM, saving the padconf only needs to be done when the padconf
changes[1].

module and the PRCM_MPU local PRCM. Add this PRCM partition
information to each OMAP4 powerdomain record, and convert the OMAP4
powerdomain function implementations to use the OMAP4 PRM instance
functions.
Also fixes a potential null pointer dereference of pwrdm->name.
The autogeneration scripts have been updated.

In some ways, the OMAP4 PRCM register layout is quite different than
the OMAP2/3 PRCM register layout. For example, on OMAP2/3, from a
register layout point of view, all CM instances were located in the CM
subsystem, and all PRM instances were located in the PRM subsystem.
OMAP4 changes this. Now, for example, some CM instances, such as
WKUP_CM and EMU_CM, are located in the system PRM subsystem. And a
"local PRCM" exists for the MPU - this PRCM combines registers that
would normally appear in both CM and PRM instances, but uses its own
register layout which matches neither the OMAP2/3 PRCM layout nor the
OMAP4 PRCM layout.
To try to deal with this, introduce some new functions, omap4_cminst*
and omap4_prminst*. The former is to be used when writing to a CM
instance register (no matter what subsystem or hardware module it
exists in), and the latter, similarly, with PRM instance registers.
To determine which "PRCM partition" to write to, the functions take a
PRCM instance ID argument. Subsequent patches add these partition IDs
to the OMAP4 powerdomain and clockdomain definitions.
As far as I can see, there's really no good way to handle these types
of register access inconsistencies. This patch seemed like the least
bad approach.
Moving forward, the long-term goal is to remove all direct PRCM
register access from the PM code. PRCM register access should go
through layers such as the powerdomain and clockdomain code that can
hide the details of how to interact with the specific hardware
variant.
While here, rename cm4xxx.c to cm44xx.c to match the naming convention
of the other OMAP4 PRCM files.

The OMAP3 PRM module is in the WKUP powerdomain, which is always
powered when the chip is powered, so it shouldn't be necessary to save
and restore those PRM registers. Remove the PRM register save/restore
code, which should save several microseconds during off-mode
entry/exit, since PRM register accesses are relatively slow.
While doing so, move the CM register save/restore code into
CM-specific code. The CM module has been distinct from the PRM module
since 2430.
This patch includes some minor changes to pm34xx.c.

In preparation for adding OMAP4-specific PRCM accessor/mutator
functions, split the existing OMAP2/3 PRCM code into OMAP2/3-specific
files. Most of what was in mach-omap2/{cm,prm}.{c,h} has now been
moved into mach-omap2/{cm,prm}2xxx_3xxx.{c,h}, since it was
OMAP2xxx/3xxx-specific.
This process also requires the #includes in each of these files to be
changed to reference the new file name. As part of doing so, add some
comments into plat-omap/sram.c and plat-omap/mcbsp.c, which use
"sideways includes", to indicate that these users of the PRM/CM includes
should not be doing so.

Change the per-hwmod mutex to a spinlock. (The per-hwmod lock
serializes most post-initialization hwmod operations such as enable,
idle, and shutdown.) Spinlocks are needed, because in some cases,
hwmods must be enabled from timer interrupt disabled-context, such as
an ISR. The current use-case that is driving this is the OMAP GPIO
block ISR: it can trigger interrupts even with its clocks disabled,
but these clocks are needed for register accesses in the ISR to succeed.
This patch also effectively reverts commit
848240223c - this patch makes
_omap_hwmod_enable() and _omap_hwmod_init() static, renames them back
to _enable() and _idle(), and changes their callers to call the
spinlocking versions. Previously, since omap_hwmod_{enable,init}()
attempted to take mutexes, these functions could not be called while
the timer interrupt was disabled; but now that the functions use
spinlocks and save and restore the IRQ state, it is appropriate to
call them directly.

The standard omap_hwmod.c _reset() code relies on an IP block's
OCP_SYSCONFIG.SOFTRESET register bit to reset the IP block. This
works for most IP blocks on the chip, but unfortunately not all. For
example, initiator-only IP blocks often don't have any MPU-accessible
OCP-header registers, and therefore the MPU can't write to any
OCP_SYSCONFIG registers in that block. Other IP blocks, such as the
IVA and I2C, require a specialized reset sequence.
Since we need to be able to reset these IP blocks as well, allow
custom IP block reset functions to be passed into the hwmod code via a
per-hwmod-class reset function pointer, struct omap_hwmod_class.reset.
If .reset is non-null, then the hwmod _reset() code will call the custom
function instead of the standard OCP SOFTRESET-based code.
As part of this change, rename most of the existing _reset() function
code to _ocp_softreset(), to indicate more clearly that it does not work
for all cases.

There are two use-cases for this patch: the !CONFIG_PM_RUNTIME case,

and the MPU watchdog case, in which the watchdog IP block should enter
idle if watchdog coverage of kernel initialization is desired, and

Split omap2_init_common_hw() into two functions. The first,
omap2_init_common_infrastructure(), initializes the hwmod code and
data, the OMAP PM code, and the clock code and data. The second,
omap2_init_common_devices(), handles any other early device
initialization that, for whatever reason, has not been or cannot be
moved to initcalls or early platform devices.
This patch is required for the hwmod postsetup patch, which allows
board files to change the state that hwmods should be placed into at
the conclusion of the hwmod _setup() function. For example, for a
board whose creators wish to ensure watchdog coverage across the
entire kernel boot process, code to change the watchdog's postsetup
state will be added in the board-*.c file between the
omap2_init_common_infrastructure() and omap2_init_common_devices() function
calls.

Adding the twl6030-usb transceiver support for OMAP4 musb driver.
OMAP4 supports 2 types of transceiver interface.
1. UTMI: The PHY is embedded within OMAP4. The transceiver functionality
is split between the twl6030 PMIC chip and OMAP4430. The VBUS, ID pin
sensing and OTG SRP generation part is integrated in TWL6030 and UTMI PHY
functionality is embedded within the OMAP4430.
There is no direct interactions between the MUSB controller and TWL6030
chip to communicate the session-valid, session-end and ID-GND events.
It has to be done through a software by setting/resetting bits in
one of the control module register of OMAP4430 which in turn toggles
the appropriate signals to MUSB controller.
The internal transceiver has functional clocks and
powerdown bits to powerdown the PHY for power saving.
Since there is no option available for having 2 transceiver drivers
for one USB controller, internal PHY specific APIs are passed through
plaform_data function pointers to use in the twl6030-usb transceiver
driver.
2. ULPI interface is provided for off-chip transceivers.

Implement GPIO as a platform device.
GPIO APIs are used in machine_init functions. Hence it is
required to complete GPIO probe before board_init. Therefore
GPIO device register and driver register are implemented as
postcore_initcalls.
omap_gpio_init() does nothing now and this function would be
removed in the next patch as it's usage is spread across most
of the board files.
Inorder to convert GPIO as platform device, modifications are
required in clockxxxx_data.c file for OMAP1 so that device names
can be used to obtain clock instead of getting clocks by
name/NULL ptr.
Use runtime pm APIs (pm_runtime_put*/pm_runtime_get*) for enabling
or disabling the clocks, modify sysconfig settings and remove usage
of clock FW APIs.
Note 1: Converting GPIO driver to use runtime PM APIs is not done as a
separate patch because GPIO clock names are different for various OMAPs
and are different for some of the banks in the same CPU. This would need
usage of cpu_is checks and bank id checks while using clock FW APIs in
the gpio driver. Hence while making GPIO a platform driver framework,
PM runtime APIs are used directly.
Note 2: While implementing GPIO as a platform device, pm runtime APIs
are used as mentioned above and modification is not done in gpio's
prepare for idle/ resume after idle functions. This would be done
in the next patch series and GPIO driver would be made to use dev_pm_ops
instead of sysdev_class in that series only.
Due to the above, the GPIO driver implicitly relies on
CM_AUTOIDLE = 1 on its iclk for power management to work, since the
driver never disables its iclk.
This would be taken care in the next patch series (see Note 3 below).
Refer to
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg39112.html
for more details.
Note 3: only pm_runtime_get_sync is called in gpio's probe() and
pm_runtime_put* is never called. This is to make the implementation
similar to the existing GPIO code. Another patch series would be sent
to correct this.
In OMAP3 and OMAP4 gpio's debounce clocks are optional clocks. They
are enabled/ disabled whenever required using clock framework APIs
TODO:
1. Cleanup the GPIO driver. Use function pointers and register
offest pointers instead of using hardcoded values
2. Remove all cpu_is_ checks and OMAP specific macros
3. Remove usage of gpio_bank array so that only
instance specific information is used in driver code
4. Rename 'method'/ avoid it's usage
5. Fix the non-wakeup gpios handling for OMAP2430, OMAP3 & OMAP4
6. Modify gpio's prepare for idle/ resume after idle functions
to use runtime pm implentation.

Implement the suggested workaround for OMAP3 regarding to sDMA draining
issue, when the channel is disabled on the fly.
This errata affects the following configuration:
sDMA transfer is source synchronized
Buffering is enabled
SmartStandby is selected.
The issue can be easily reproduced by creating overrun situation while
recording audio.
Either introduce load to the CPU:
nice -19 arecord -D hw:0 -M -B 10000 -F 5000 -f dat > /dev/null & \
dd if=/dev/urandom of=/dev/null
or suspending the arecord, and resuming it:
arecord -D hw:0 -M -B 10000 -F 5000 -f dat > /dev/null
CTRL+Z; fg; CTRL+Z; fg; ...
In case of overrun audio stops DMA, and restarts it (without reseting
the sDMA channel). When we hit this errata in stop case (sDMA drain did
not complete), at the coming start the sDMA will not going to be
operational (it is still draining).
This leads to DMA stall condition.
On OMAP3 we can recover with sDMA channel reset, it has been observed
that by introducing unrelated sDMA activity might also help (reading
from MMC for example).
The same errata exists for OMAP2, where the suggestion is to disable the
buffering to avoid this type of error.
On OMAP3 the suggestion is to set sDMA to NoStandby before disabling
the channel, and wait for the drain to finish, than configure sDMA to
SmartStandby again.

An errata workaround for omap24xx is not setting the buffering disable bit
25 what is the purpose but channel enable bit 7 instead.
Background for this fix is the DMA stalling issue with ASoC omap-mcbsp
driver. Peter Ujfalusi <peter.ujfalusi@nokia.com> has found an issue in
recording that the DMA stall could happen if there were a buffer overrun
detected by ALSA and the DMA was stopped and restarted due that. This
problem is known to occur on both OMAP2420 and OMAP3. It can recover on
OMAP3 after dma free, dma request and reconfiguration cycle. However, on
OMAP2420 it seems that only way to recover is a reset.
Problem was not visible before the commit c12abc0. That commit changed that
the McBSP transmitter/receiver is released from reset only when needed. That
is, only enabled McBSP transmitter without transmission was able to prevent
this DMA stall problem in receiving side and underlying problem did not show
up until now. McBSP transmitter itself seems to no be reason since DMA
stall does not recover by enabling the transmission after stall.
Debugging showed that there were a DMA write active during DMA stop time and
it never completed even when restarting the DMA. Experimenting showed that
the DMA buffering disable bit could be used to avoid stalling when using
source synchronized transfers. However that could have performance hit and
OMAP3 TRM states that buffering disable is not allowed for destination
synchronized transfers so subsequent patch will implement a method to
complete DMA writes when stopping.
This patch is based on assumtion that complete lock-up on OMAP2420 is
different but related problem. I don't have access to OMAP2420 errata but
I believe this old workaround here is put for a reason but unfortunately
a wrong bit was typed and problem showed up only now.

Only OMAP2+ platforms have the System Control Module (SCM) IP block.
In the past, we've kept the SCM header file in plat-omap. This has
led to abuse - device drivers including it; includes being added that
create implicit dependencies on OMAP2+ builds; etc.
In response, move the SCM headers into mach-omap2/.
As part of this, remove the direct SCM access from the OMAP UDC
driver. It was clearly broken. The UDC code needs an indepth review for
use on OMAP2+ chips.

Previously the OMAP McBSP ASoC driver implemented CLKS switching by
using omap_ctrl_{read,write}l() directly. This is against policy; the OMAP
System Control Module functions are not intended to be exported to drivers.
These symbols are no longer exported, so as a result, the OMAP McBSP ASoC
driver does not build as a module.
Resolve the CLKS clock changing portion of this problem by creating a
clock parent changing function that lives in
arch/arm/mach-omap2/mcbsp.c, and modify the ASoC driver to use it.
Due to the unfortunate way that McBSP support is implemented in ASoC
and the OMAP tree, this symbol must be exported for use by
sound/soc/omap/omap-mcbsp.c.
Going forward, the McBSP device driver should be moved from
arch/arm/*omap* into drivers/ or sound/soc/* and the CPU DAI driver
should be implemented as a platform_driver as many other ASoC CPU DAI
drivers are. These two steps should resolve many of the layering
problems, which will rapidly reappear during a McBSP hwmod/PM runtime
conversions.

The OMAP ASoC McBSP code implemented CLKR and FSR signal muxing via
direct System Control Module writes on OMAP2+. This required the
omap_ctrl_{read,write}l() functions to be exported, which is against
policy: the only code that should call those functions directly is
OMAP core code, not device drivers. omap_ctrl_{read,write}*() are no
longer exported, so the driver no longer builds as a module.
Fix the pinmuxing part of the problem by removing calls to
omap_ctrl_{read,write}l() from the OMAP ASoC McBSP code and
implementing signal muxing functions in arch/arm/mach-omap2/mcbsp.c.

In OMAP4, as per new PM programming model, the legacy registers
which were there in OMAP3 are all shifted by 0x100 while new one's
are added from offset 0 to 0x10.
For OMAP4, the register offset appending of 0x100 done in devices.c
currently, is moved to driver file.This change fits in for current
implementation as well as once the driver undergoes hwmod adaptation.

This patch adds driver support for OMAP2/3/4 high speed UART.
The driver is made separate from 8250 driver as we cannot
over load 8250 driver with omap platform specific configuration for
features like DMA, it makes easier to implement features like DMA and
hardware flow control and software flow control configuration with
this driver as required for the omap-platform.
This patch involves only the core driver and its dependent.

On omap4 control module is divided in four IP blocks.

- CTRL_MODULE_PAD_CORE 0x4a100000
- CTRL_MODULE_WKUP 0x4a30c000
- CTRL_MODULE_PAD_WKUP 0x4a31e000
Addressing all the modules with single base address is not possible
considering 16 bit offsets. The mux code manages the pad core and pad
wakeup related base address inside the mux framework. For other usage
only control core and control pad bases are necessary. So this patch
maps only needed pad control base address which is used by device drivers
and infrastructure code
The main control core base is still kept same in this patch to
keep git-bisect working. This will be fixed in the relevant patch
in this series.

In order to help differentiate omap_devices from normal
platform_devices, make them all a parent of a new common parent
device.
Then, in order to determine if a platform_device is also an
omap_device, checking the parent is all that is needed.
Users of this feature are the runtime PM core for OMAP, where we need
to know if a device being passed in is an omap_device or not in order
to know whether to call the omap_device API with it.
In addition, all omap_devices will now show up under /sys/devices/omap
instead of /sys/devices/platform

This reverts commit 0007122ad8.
The dereference method of checking for a valid omap_device when
wrapping a platform_device is rather unsafe and dangerous.
Instead, a better way of checking for a valid omap-device is
to use a common parent device for all omap_devices, then a check
can simply be made using the device parent. The only user of this
API was the initial version of the runtime PM core for OMAP. This
has now been switched to check device parent, so there are no more
users of this API.

Some modules (like GPIO, DSS...) require optionals clock to be enabled
in order to complete the sofreset properly.
Add a HWMOD_CONTROL_OPT_CLKS_IN_RESET flag to force all optional clocks
to be enabled before reset. Disabled them once the reset is done.
TODO:
For the moment it is very hard to understand from the HW spec, which
optional clock is needed and which one is not. So the current approach
will enable all the optional clocks.
Paul proposed a much finer approach that will allow to tag only the needed
clock in the optional clock table. This might be doable as soon as we have
a clear understanding of these dependencies.

In OMAP3 a specific SYSSTATUS register was used to get the softreset status.
Starting in OMAP4, some IPs does not have SYSSTATUS register and instead
use the SYSC softreset bit to provide the status.
Other cases might exist:
- Some IPs like McBSP does have a softreset control but no reset status.
- Some IPs that represent subsystem, like the DSS, can contains
a reset status without softreset control. The status is the aggregation
of all the sub modules reset status.
- Add a new flag (SYSC_HAS_RESET_STATUS) to identify the new programming model
and replace the previous SYSS_MISSING, that was used to flag IP with
softreset control but without the SYSSTATUS register, with a specific
SYSS_HAS_RESET_STATUS flag.
- MCSPI and MMC contains both programming models, so the legacy one
will be prevented by removing the syss offset field that become useless.

Expose an hardreset API from hwmod in order to assert / deassert all the

Most processor IPs does have a hardreset signal controlled by the PRM.
This is different of the softreset used for local IP reset from the
SYSCONFIG register.
The granularity can be much finer than orginal HWMOD, for ex, the IVA
hwmod contains 3 reset lines, the IPU 3 as well, the DSP 2...
Since this granularity is needed by the driver, we have to ensure
than one hwmod exist for each hardreset line.
- Store reset lines as hwmod resources that a driver can query by name like
an irq or sdma line.
- Add two functions for asserting / deasserting reset lines in hwmods
processor that require manual reset control.
- Add one functions to get the current reset state.
- If an hwmod contains only one line, an automatic assertion / de-assertion
is done.
-> de-assert the hardreset line only during enable from disable transition
-> assert the hardreset line only during shutdown
Note: The hwmods with hardreset line and HWMOD_INIT_NO_RESET flag must be
kept in INITIALIZED state.
They can be properly enabled only if the hardreset line is de-asserted
before.

Currently omap_hwmod_mutex is being used to protect both the list

patch separates these two types of locking.
First, omap_hwmod_mutex is used only to protect access and
modification of omap_hwmod_list. Also cleaned up some comments
referring to this mutex that are no longer needed.
Then, for protecting concurrent access to hwmod functions, use a
per-hwmod mutex. This protects concurrent access to a single hwmod,

This patch extends the ASoC API to allow sound cards to have more than one
CODEC and more than one platform DMA controller. This is achieved by dividing
some current ASoC structures that contain both driver data and device data into
structures that only either contain device data or driver data. i.e.
struct snd_soc_codec ---> struct snd_soc_codec (device data)
+-> struct snd_soc_codec_driver (driver data)
struct snd_soc_platform ---> struct snd_soc_platform (device data)
+-> struct snd_soc_platform_driver (driver data)
struct snd_soc_dai ---> struct snd_soc_dai (device data)
+-> struct snd_soc_dai_driver (driver data)
struct snd_soc_device ---> deleted
This now allows ASoC to be more tightly aligned with the Linux driver model and
also means that every ASoC codec, platform and (platform) DAI is a kernel
device. ASoC component private data is now stored as device private data.
The ASoC sound card struct snd_soc_card has also been updated to store lists
of it's components rather than a pointer to a codec and platform. The PCM
runtime struct soc_pcm_runtime now has pointers to all its components.
This patch adds DAPM support for ASoC multi-component and removes struct
snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec
or runtime PCM level basis rather than using snd_soc_socdev.
Other notable multi-component changes:-
* Stream operations now de-reference less structures.
* close_delayed work() now runs on a DAI basis rather than looping all DAIs
in a card.
* PM suspend()/resume() operations can now handle N CODECs and Platforms
per sound card.
* Added soc_bind_dai_link() to bind the component devices to the sound card.
* Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove
DAI link components.
* sysfs entries can now be registered per component per card.
* snd_soc_new_pcms() functionailty rolled into dai_link_probe().
* snd_soc_register_codec() now does all the codec list and mutex init.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform driver
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().

Add omap_pm_set_min_clk_rate(). This constraint is meant for use by
device drivers to translate a certain device-specific performance
constraint (e.g., "minimum polygons per second") to a clock rate for
the driver's device, given the driver's intimate knowledge of the
device hardware (e.g., device type, device hardware revision, firmware
revision, etc.) From a general PM core perspective, clock rate is
probably the closest general analog to "performance" that is
available, but the exact mapping from a use-case-specific performance
constraint to clock rate must be done by the driver. Drivers intended for
upstream merging shouldn't hardcode specific clock rates in their code
without basing those rates on some performance criteria requested through
the driver's subsystem (ideally, from userspace).
Imre Deak <imre.deak@nokia.com> described the need and use-case for
this constraint, and discussed the implementation - thanks, Imre.

Add return values to the PM constraint functions. This allows the PM
core to provide feedback to the caller if a constraint is not
possible. Update the one upstream user of omap_pm_set_max_mpu_wakeup_lat()
to add a compatibility wrapper, needed until the driver is changed.
Update some of the documentation to conform more closely to kerneldoc style.
Add an additional device parameter to omap_pm_set_max_dev_wakeup_lat()
to identify the device requesting the constraint. This is so repeated calls
to omap_pm_set_max_dev_wakeup_lat() with the same requesting device can
override the device's previously-set constraint. Also, it allows the PM
core to make a decision as to whether or not the constraint should be
satisfied, based on the caller's identity.

Add omap_device_get_mpu_rt_va(). This is intended to be used by
device drivers (currently, via a struct platform_data function
pointer) to retrieve their corresponding device's virtual base address
that the MPU should use to access the device. This is needed because
the omap_hwmod code does its own ioremap(), in order to gain access to
the module's OCP_SYSCONFIG register.
Add omap_hwmod_get_mpu_rt_va(). omap_device_get_mpu_rt_va() calls this
function to do the real work.
While here, rename struct omap_hwmod._rt_va to struct
omap_hwmod._mpu_rt_va, to reinforce that it refers to the MPU's
register target virtual address base (as opposed to, for example, the
L3's).
In the future, this belongs as a function in an omap_bus, so it is not
necessary to call this through a platform_data function pointer.

On kernels that don't use the omap_device_enable() calls to enable
devices, leave all on-chip devices enabled in hwmod _setup().
Otherwise, accesses to those devices are likely to fail, crashing the
system. It's expected that kernels built without CONFIG_PM_RUNTIME
will be the primary use-case for this. This functionality is
controlled by adding an extra parameter to omap_hwmod_late_init().
This patch is based on the patch "OMAP: hwmod: don't auto-disable

Some hwmods may need to be idled/enabled in atomic context, so
non-locking versions of these functions are required.
Most users should not need these and usage of theses should be
controlled to understand why access is being done in atomic context.
For this reason, the non-locking functions are only exposed at the
hwmod level and not at the omap-device level.
The use-case that led to the need for the non-locking versions is
hwmods that are enabled/idled from within the core idle/suspend path.
Since interrupts are already disabled here, the mutex-based locking in
hwmod can sleep and will cause potential deadlocks.

The DEFAULT_RATE clksel_rate flag is essentially useless. It was set
on some of the lowest divisors, which, when switching to a much
higher-rate parent, could have potentially resulted in rates that
exceeded the hardware specifications for downstream clocks in the
window between the clk_set_parent(), and a subsequent clk_set_rate().
It seems much safer to just remove the flag and always use the highest
available divisor (resulting in the lowest possible rate) after the
switch, and this patch does so.
Ideally, it would be best to first attempt to switch to a divisor that
matches the clock's rate with the previous parent, if at all possible.
But that is a project for some other day or some other person. The
parent changing code is rarely used.

This removes the dependency to the UART1 being available for storing
the debug configuration in uncompress.h. This will simplify the
DEBUG_LL UART configuration for boards that may not have UART1, or
have an external UART as it requires only one mapping for DEBUG_LL.
The patch has a few limitations. Basically now we're assuming that
the kernel uncompress code won't overlap with OMAP_UART_INFO. We also
assume the printascii is called at least once before paging_init in
order for addruart to have a chance to read the UART setup from
OMAP_UART_INFO.

tends to bear some resemblance to what is used in the OMAP TRMs. This
patch adds a non-exported function to the OMAP clock code,
omap_clk_get_by_name(). A subsequent patch will convert the hwmod
code to use this function.
This function is for use only by core code, and practically, no other
code outside the hwmod code should need it. Device driver code in the
kernel must not use this function, which is why it is not exported.
Drivers should use the appropriate clock alias provided by the clkdev
data structures, so driver code can be completely SoC-independent.

The RATE_FIXED clock flag is pointless. In the OMAP1 clock code, it
simply causes the omap1_clk_round_rate() function to return the
current rate of the clock. omap1_clk_round_rate(), however, should
never be called for a fixed-rate clock, since none of these clocks
have a .round_rate function pointer set in their struct clk records.
Similarly, in the OMAP2+ clock code, the RATE_FIXED flag just causes
the clock code to emit a warning if the OMAP clock maintainer was
foolish enough to add a .round_rate function pointer to a fixed-rate
clock. "Doctor, it hurts when I pretend that a fixed-rate clock is
rate-changeable." "Then don't pretend that a fixed-rate clock is
rate-changeable." It has no functional value. This patch drops the
RATE_FIXED clock flag, removing it from all clocks that are so marked.

All of the clocks that are marked with DELAYED_APP are changed as part
of the virt_prcm_set OPP virtual clock. On 24xx, these clocks all
need to be changed as part of a group to keep the clock tree
functional - hence the need for the VALID_CONFIG bit, which is not
present on later OMAPs. These clocks should not be rate-changed
independently. So prevent these clocks from being changed
independently by dropping their .round_rate and .set_rate function
pointers. It then turns out that the DELAYED_APP clock flag is no
longer useful, so drop it and the associated code and renumber the
clock flags.

It turns out that the only purpose of the CONFIG_PARTICIPANT clock
flag is to prevent omap2_clk_set_rate() and omap2_clk_set_parent()
from being executed on clocks with that flag set. The rate-changing
component can be more directly accomplished by dropping the .set_rate
and .round_rate function pointers from those CONFIG_PARTICIPANT struct
clks. As far as the parent-changing component is concerned, it turns
out that none of the CONFIG_PARTICIPANT clocks have multiple parent
choices, so all that is necessary is for omap2_clk_set_parent() to
bail out early if the new parent is equal to the old parent.
Implement this change and get rid of the flag, which has always had a
confusing name (it appears to be a Kconfig option, falsely).

The maximum DPLL multiplier (M) values for OMAP2xxx and OMAP3xxx are
one increment higher than they should be. See for example the
OMAP242x TRM Rev X Section 5.10.6 "Clock Generator Registers" and the
OMAP36xx TRM Rev C Table 3-202 "CM_CLKSEL1_PLL". Programming a 0 into
the DPLL's M register bitfield is valid for OMAP2/3 and indicates that
the DPLL should enter MN-bypass mode. Also, increase the minimum
multiplier (M) value for the DPLL rate rounding code from 1 to 2, to
ensure that it does not inadvertently put the DPLL into bypass.
Note that the register documentation in the OMAP2xxx and OMAP3xxx TRMs
does not make clear that the actual DPLL divider value (the "N") is
the content of the appropriate register bitfield for the N value,
_plus one_. (In other words, an N register bitfield of 0 indicates a
DPLL divider value of 1.) This is only clearly documented in the
OMAP4430 TRM, in, for example, OMAP4430 TRM Rev A Table 3-1167
"CM_CLKSEL_DPLL_USB".
While here, update copyrights, add kerneldoc for struct dpll_data,
drop the unused struct dpll_data.max_tolerance field, remove some
unnecessary #includes in DPLL-related code, and replace the #include
of <linux/module.h> with <linux/list.h>, which is what was really
needed. The OMAP4 clock autogenerator script has been updated

In OMAP3 Some modules like Smartreflex do not have the regular sysconfig
register.Instead clockactivity bits are part of another register at a
different bit position than the usual bit positions 8 and 9.
In OMAP4, a new scheme is available due to the new protocol
between the PRCM and the IPs. Depending of the scheme, the SYSCONFIG
bitfields position will be different.
The IP_REVISION register should be at offset 0x00.
It should contain a SCHEME field. From this we can determine whether
the IP follows legacy scheme or the new scheme.
31:30 SCHEME Used to distinguish between old scheme and current.
Read 0x0: Legacy protocol.
Read 0x1: New PRCM protocol defined for new OMAP4 IPs
For legacy IP
13:12 MIDLEMODE
11:8 CLOCKACTIVITY
6 EMUSOFT
5 EMUFREE
4:3 SIDLEMODE
2 ENAWAKEUP
1 SOFTRESET
0 AUTOIDLE
For new OMAP4 IP's, the bit position in SYSCONFIG is (for simple target):
5:4 STANDBYMODE (Ex MIDLEMODE)
3:2 IDLEMODE (Ex SIDLEMODE)
1 FREEEMU (Ex EMUFREE)
0 SOFTRESET
Unfortunately In OMAP4 also some IPs will not follow any of these
two schemes. This is the case at least for McASP, SmartReflex
and some security IPs.
This patch introduces a new field sysc_fields in omap_hwmod_sysconfig which
can be used by the hwmod structures to specify the offsets for the
sysconfig register of the IP.Also two static structures
omap_hwmod_sysc_type1 and omap_hwmod_sysc_type2 are defined
which can be used directly to populate the sysc_fields if the IP follows
legacy or new OMAP4 scheme. If the IP follows none of these two schemes
a new omap_hwmod_sysc_fields structure has to be defined and
passed as part of omap_hwmod_sysconfig.

The omap_device struct contains a 'struct platform_device'. Normally,
converting a platform_device pointer to an omap_device pointer
consists of simply doing a container_of(), as is done currently by the
to_omap_device() macro.
However, if this is attempted when using platform_device that has not
been created as part of the omap_device creation, the container_of()
will point to a memory location before the platform_device pointer
which will contain random data.
Therefore, we need a way to detect valid omap_device pointers. This
patch solves this by using the simple magic number approach.

First, this patch adds new worst-case latency values to the
omap_device_pm_latency struct. Here the worst-case measured latencies
for the activate and deactivate hooks are stored.
In addition, add an option to auto-adjust the latency values used for
device activate/deactivate.
By setting a new 'OMAP_DEVICE_LATENCY_AUTO_ADJUST' flag in the
omap_device_pm_latency struct, the omap_device layer automatically
adjusts the activate/deactivate latencies to the worst-case measured
values.
Anytime a new worst-case value is found, it is printed to the console.
Here is an example log during boot using UART2 s an example. After
boot, the OPP is manually changed to the 125MHz OPP:
[...]
Freeing init memory: 128K
omap_device: serial8250.2: new worst case deactivate latency 0: 30517
omap_device: serial8250.2: new worst case activate latency 0: 30517
omap_device: serial8250.2: new worst case activate latency 0: 218139648
omap_device: serial8250.2: new worst case deactivate latency 0: 61035
omap_device: serial8250.2: new worst case activate latency 0: 278076171
omap_device: serial8250.2: new worst case activate latency 0: 298614501
omap_device: serial8250.2: new worst case activate latency 0: 327331542
/ # echo 125000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed
omap_device: serial8250.2: new worst case deactivate latency 0: 91552
Motivation: this can be used as a technique to automatically determine
the worst case latency values. The current method of printing a
warning on every violation is too noisy to actually interact the
console in order to set low OPP to discover latencies.
Another motivation for this patch is that the activate/deactivate
latenices can vary depending on the idlemode of the device. While
working on the UARTs, I noticed that when using no-idle, the activate
latencies were as high as several hundred msecs as shown above. When
the UARTs are in smart-idle, the max latency is well under 100 usecs.

Add usecounting for wakeup and sleep dependencies. In the current
situation, if several functions add dependencies on the same
clockdomains, when the first dependency removal function is called,
the dependency will be incorrectly removed from the hardware.
Add clkdm_clear_all_wkdeps() and clkdm_clear_all_sleepdeps(), which
provide a fast and usecounting-consistent way to clear all hardware
clockdomain dependencies, since accesses to these registers can be
quite slow. pm{2,3}4xx.c has been updated to use these new functions.
The original version of this patch did not touch these files, which
previously wrote directly to the wkdep registers, and thus confused
the usecounting code. This problem was found by Kevin Hilman
<khilman@deeprootsystems.com>.
N.B.: This patch introduces one significant functional difference over
the previous pm34xx.c code: sleepdeps are now cleared during
clockdomain initialization, whereas previously they were left
untouched. This has been tested by Kevin and confirmed to work.
The original version of this patch also did not take into
consideration that some clockdomains do not have sleep or wakeup
dependency sources, which caused NULL pointer dereferences. This
problem was debugged and fixed by Kevin Hilman
<khilman@deeprootsystems.com>.

Move clockdomain wakeup dependency and sleep dependency data
structures from the powerdomain layer to the clockdomain layer, where
they belong. These dependencies were originally placed in the
powerdomain layer due to unclear documentation; however, it is clear
now that these dependencies are between clockdomains. For OMAP2/3,
this is not such a big problem, but for OMAP4 this needs to be fixed.

In the current implementation the sysconfig value is read into
_sysc_cache once and an actual update to the sysconfig register
happens only if the new value paased is differnt from the one in _sysc_cache.
_sysc_cache is updated only if _HWMOD_SYSCONFIG_LOADED is not set.
This can lead to the follwing issue if off mode is enabled in modules
which employs "always-retore" mechanism of context save and restore.
a. The module sets the sysconfig register through omap_device_enable.
Here _sysc_cache is updated with the value written to the sysconfig
register and left.
b. The power domain containig the module enters off mode and the
module context is lost.
c. The module in use becomes active and calls omap_device_enable to
enable itself. Here a read of sysconfig register does not happen
as _HWMOD_SYSCONFIG_LOADED flag is set. The value to be written
to the sysconfig register will be same as the one written in step a.
Since _sysc_cache reflects the previous written value an update
of the sysconfig register does not happen.
This means in modules which employs "always-restore" mechanism
after off , the sysconfig regsiters will never get updated.
This patch introduces a flag SYSC_NO_CACHE which if set ensures that the
sysconfig register is always read into _sysc_cache before an update is
attempted.
This flags need to be set only by modules which does not do a context save
but re-initializes the registers every time the module is accessed. This
includes modules like i2c, smartreflex etc.

After this patch, the hwmod code will set the module AUTOIDLE bit

enable. If the hwmod flag HWMOD_NO_OCP_AUTOIDLE is set, AUTOIDLE will
be set to 0 upon enable. Upon module disable, AUTOIDLE will be set to
1.
Enabling module autoidle should save some power. The only reason to

include/linux/omapfb.h - ioctls etc for userspace and some kernel
stuff for board files
drivers/video/omap/omapfb.h - for omapfb internal use
This cleans up omapfb.h and also makes it easier for the upcoming new
DSS driver to co-exist with the old driver.

Added runtime programming for the differences in EHCI interface between
OMAP3EVM revisions (Rev >= E) and (Rev < E).
Changes:
- EHCI PHY reset GPIO pin is 21 on Rev >= E while Rev < E
uses GPIO pin 135.
- Rev >= E uses EHCI Vbus enable GPIO22 line.
- Rev >= E uses GPIO61 to select EHCI port either on main board or
on Mistral Daughter Card (MDC). OMAP3EVM Rev < E doesn't have
EHCI port on main board.
- Currently GPIO61 it programmed to enable EHCI port on main
board only.

All of the OMAP3 IVA physical address macros in
plat-omap/include/plat/omap34xx.h are wrong[1]:
OMAP34XX_IVA_INTC_BASE: The IVA interrupt controller does not appear
to be accessible from the L3 interconnect, and in any case is
definitely not at 0x40000000; the latter address appears to be the
internal IVA physical address base for the OMAP2420's interrupt control[2].
OMAP34XX_DSP_BASE: The section of L3 physical address space mapped to
the IVA starts at 0x5c000000, not 0x58000000.
OMAP34XX_DSP_MEM_BASE: It's not clear what this refers to, but it's not
in the L3 IVA address space.
OMAP34XX_DSP_IPI_BASE: The Intrusive Port Interface is a relic from
the OMAP2420 days and no longer applies to OMAP3.
OMAP34XX_DSP_MMU_BASE: The DSP MMU is mapped at 0x5d000000, not 0x5a000000.
Nothing that uses these can possibly be working, so drop them. When
future code needs these, correct versions can be added in.

OMAP3630 is the latest in the family of OMAP3 devices
and among the changes it introduces are:
New OPP levels for new voltage and frequency levels. a bunch of
Bug fixes to various modules feature additions, notably with ISP,
sDMA etc.
Details about the chip is available here:
http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12836&contentId=52606
Strategy used:
Strategy to introduce this device into Linux was discussed here:
Ref: http://marc.info/?t=125343303400003&r=1&w=2
Two approaches were available:
a) Consider 3630 generation of devices as a new family of silicon
b) Consider 3630 as an offshoot of 3430 family of devices
As a common consensus, (b) seems to be more valid for 3630 as:
* There are changes which are easily handled by using "FEATURES"
infrastructure.
For details how to do this, see thread:
http://marc.info/?t=125050998500001&r=1&w=2
* Most of existing 34xx infrastructure can be reused(almost 90%+)
- so no ugly if (cpu_is_omap34xx() || cpu_is_omap36xx())
all over the place
- lesser chance of bugs due to reuse of proven code flow
- 36xx specific handling can still be done where required
within the existing infrastructure
NOTE:
* If additional 34xx series are added, OMAP3430_REV_ESXXXX can be
added on top of the existing 3630 ones are renumbered
This patch was tested on SDP3430, boot tested on 3630 platform using
3430sdp defconfig

The MMC mux pins normally used by omap chips in devices.c
are different from what is needed by omap7xx chips. This
change adds a conditional around the mux setup code to
enable the correct mux pins.
The omap730 and omap850 both use a different clock for the "fck"
clock of the MMC interface than other omap processors based on the
SOFT_REQ_REG, pin 12. The "ick" clock is the same as that used
by other omap processors.
* Added the missing clock definition as mmc3_ck to clock.h
* Added the clock definition to omap_clks in clock.c
* Added CK_7XX to the mmci-omap.0 "ick" clock already in clock.c
With these changes, it is now possible to initialize and use MMC
cards with omap730 and omap850 devices.

So these boards should not have "Uncompressing Kernel...."

unnecessary writes to omap uarts is avoided.

Eliminate OMAP_MAX_NR_PORTS
Note that also the null terminator entry for omap1
serial_platform_data needs to be now removed to avoid
oopsing.
Note that mach-omap1 uses struct plat_serial8250_port
array, which requires a null terminator at the end,
and that's why we need to use ARRAY_SIZE - 1. This
is not needed on mach-omap2 as the array used is
struct omap_uart_state, and does not use a null
terminator.

Due to an OMAP3 errata (1.142), on HS/EMU devices SDRC should be
programed to issue automatic self refresh on timeout
of AUTO_CNT = 1 prior to any transition to OFF mode.
This is needed only on sil rev's ES3.0 and above.
This patch enables the above needed WA in the SDRC power register
value stored in scratchpad, so that ROM code restores this value
in SDRC POWER on the wakeup path.
The original SDRC POWER register value is stored and restored back
in omap_sram_idle() function.
