Fix up various conflicts in
- arch/arm/mach-omap2/board-omap3evm.c
- arch/arm/mach-omap2/clock3xxx_data.c
- arch/arm/mach-omap2/usb-musb.c
- arch/arm/plat-omap/include/plat/usb.h
- drivers/usb/musb/musb_core.h
This is a first pass at reorganizing mach-omap2/voltage.c:
- Separate almost all of the data from the code of mach-omap2/voltage.c.
The code remains in mach-omap2/voltage.c. The data goes into one
of several places, depending on what type of data it is:
- Silicon process/validation data: mach-omap2/opp*_data.c
- VC (Voltage Controller) data: mach-omap2/vc*_data.c
- VP (Voltage Processor) data: mach-omap2/vp*_data.c
- Voltage domain data: mach-omap2/voltagedomains*_data.c
The ultimate goal is for all this data to be autogenerated, the same
way we autogenerate the rest of our data.
- Separate VC and VP common data from VDD-specific VC and VP data.
- Separate common voltage.c code from SoC-specific code; reuse common code.
- Reorganize structures to avoid unnecessary memory loss due to unpacked
fields.
There is much left to be done. VC code and VP code should be separated out
into vc*.c and vp*.c files. Many fields in the existing structures are
superfluous, and should be removed. Some code in voltage.c seems to be
duplicated; that code should be moved into functions of its own. Proper
voltage domain code should be created, as was done with the powerdomain
and clockdomains, and powerdomains should reference voltagedomains.

On OMAP4, the dpll post divider outputs (MX outputs)
along with clockout_x2 output provide a way to allow/deny
hardware level autogating.
Allowing autoidle would mean that the hw would autogate
this clock when there is no dependency for it.
Denying idle would mean that this clock output will be
forced to stay enabled.
Add dpll api's to read/allow/deny idle control
for these dpll mx postdividers.
NOTE: The gatectrl bit set to 0 allows gatectrl,
and the bit set to 1 denies gatectrl.

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.

[khilman: fixed link error for OMAP2-only defconfig]
Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
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.

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.

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.

Craneboard is a hardware development platform based on the
Sitara AM3517 ARM Cortex - A8 microprocessor device. This is a
low cost reference design.
This patch adds basic board file. Detailed support will follow in
subsequent patches.

They are extremely similar anyway, let's get rid
of one file.
While at that, also remove the empty zoom_config
variable.
