This patch fixes the checkpatch errors listed below:

ERROR: space required before the open parenthesis '('
ERROR: need consistent spacing around '+' (ctx:WxV)
ERROR: space prohibited before that close parenthesis ')'

Also, following warning is fixed by adding 'platid' variable
which can reduce number of lines exceeding 80 characters.

94e948e6e4 s3fb: fix Virge/GX2
Fix Virge/GX2 support in s3fb:
- fix IDs: 86C357 is GX2, 86C359 is GX2+, 86C356 probably does not exist
- add memory size detection
- drive it the same way as Trio3D/2X

The original IDs most likely came from S3 website which claims that:
- 356 is Virge/GX2 with ID=8A10, driver included in Windows 2K, XP
- 357 is Virge/GX2+ with ID=8A11, driver included in Windows ME
- 359 is Virge/GX2+ with ID=8A12, driver included in Windows ME
but:
- google search for 86C356 only reveals references to Trio3D (probably
because of a typo - Trio3D is 86C365)
- my card is clearly marked as 86C357, Virge/GX2 and has ID=8A10
- there is no driver for IDs 8A11 and 8A12 in Windows ME
- there is a driver for ID 8A10 in Windows ME that says it's GX2 (357)

Tested with #9 Reality 334 (86C357 Virge/GX2, ID=0x8A10).

247f993861 fbdev: sh_mobile_lcdcfb: fix module lock acquisition
Whenever the LCDC is to be started or stopped, a board callback is
checked for existence and invoked. Prior to the invokation, the
callback's module lock is also acquired, to be released once the
callback returns. However, the order of testing makes it possible for
the lock to be acquired and not released in case the callback does not
exist. This patch reorders the tests to prevent this particular case.

b692a63af8 viafb: add VIA slapping capability
This patch introduces dummy functions to execute when we don't know
what we should do (due to missing documentation). They do nothing
but print a nice message in the log explaining the situation.
To trigger this message initial power management support is
activated which might save a bit energy by disabling PLL and clock
if no device is configured to use them.

Note: The message is only shown for the oldest IGPs CLE266 and K400
      as for the other platforms there are reasonable assumptions
      how it does (hopefully) work.

33ee3b2e2e kstrto*: converting strings to integers done (hopefully) right
1. simple_strto*() do not contain overflow checks and crufty,
   libc way to indicate failure.
2. strict_strto*() also do not have overflow checks but the name and
   comments pretend they do.
3. Both families have only "long long" and "long" variants,
   but users want strtou8()
4. Both "simple" and "strict" prefixes are wrong:
   Simple doesn't exactly say what's so simple, strict should not exist
   because conversion should be strict by default.

The solution is to use "k" prefix and add convertors for more types.
Enter
	kstrtoull()
	kstrtoll()
	kstrtoul()
	kstrtol()
	kstrtouint()
	kstrtoint()

	kstrtou64()
	kstrtos64()
	kstrtou32()
	kstrtos32()
	kstrtou16()
	kstrtos16()
	kstrtou8()
	kstrtos8()

Include runtime testsuite (somewhat incomplete) as well.

strict_strto*() become deprecated, stubbed to kstrto*() and
eventually will be removed altogether.

Use kstrto*() in code today!

Note: on some archs _kstrtoul() and _kstrtol() are left in tree, even if
      they'll be unused at runtime. This is temporarily solution,
      because I don't want to hardcode list of archs where these
      functions aren't needed. Current solution with sizeof() and
      __alignof__ at least always works.

ef0a5e80f5 pwm_backlight: add check_fb() hook
In systems with multiple framebuffer devices, one of the devices might be
blanked while another is unblanked.  In order for the backlight blanking
logic to know whether to turn off the backlight for a particular
framebuffer's blanking notification, it needs to be able to check if a
given framebuffer device corresponds to the backlight.

This plumbs the check_fb hook from core backlight through the
pwm_backlight helper to allow platform code to plug in a check_fb hook.

23a9847f0d mbp_nvidia_bl: remove DMI dependency
This driver only has to deal with two different classes of hardware, but
right now it needs new DMI entries for every new machine. It turns out
that there's an ACPI device that uniquely identifies Apples with backlights,
so this patch reworks the driver into an ACPI one, identifies the hardware
by checking the PCI vendor of the root bridge and strips out all the DMI
code. It also changes the config text to clarify that it works on devices
other than Macbook Pros and GPUs other than nvidia.

32b98bf875 fbcon: fix situation where fbcon gets deinitialised and can't reinit.
Situation as follow:
2 GPUs + vesafb + kms.

GPU 1 is primary, vesafb binds to it as fb0
radeon loads
GPU 0 loads as fb1
GPU 1 loads, vesafb gets kicked off which causes fb0 to unbind
console, which causes the dummy console to rebind.

this means fbcon_deinit gets called, which calls fbcon_exit
since the console isn't bound anymore and we set fbcon_has_exited.

GPU 1 creates a new fb0 which is primary and we want to be console.
fbcon_fb_registered gets called sets the primary up and calls set_con2fb_map,
however as fbcon_has_exited is set nothing further ever happens.

This patch bypasses the fbcon_has_exited and checks if the console is unbound,
if its unbound it calls the fbcon_takeover which calls the vt layer to
call the fbcon_startup method and everthing works.

dfc906daee video: Fix EDID macros H_SYNC_WIDTH and H_SYNC_OFFSET
The macros for getting the values for horizontal sync width and offset
do not respect the EDID specification. Both these values are 10 bit
values according to [1], not 6 bit values. The lower 8 bits are stored
in byte 8 and byte 9 of the DTD respectively, while two additional bits
for each value are stored in byte 11. The original macros just slammed
the bits together.

Although the original macros usually worked fine because the higher two
bits are rarely used, it can cause severe problems on plasma panels
running at 1920x1080 @ 50 Hz with drivers that rely on the correct
parsing of the EDID data by fbmon.c (e.g. udlfb).

The patch should apply cleanly to both the fbdev-2.6.git branch and
linux-next.git branch.

803a4e14a7 uvesafb,vesafb: create WC or WB PAT-entries
with an PAT-enabled kernel, when using uvesafb or vesafb, these drivers will
create uncached-minus PAT entries for the framebuffer memory because they use
ioremap() (not the *_cache or *_wc variants). When the framebuffer memory
intersects with the video RAM used by Xorg, the complete video RAM will be
mapped uncached-minus what results in a serve performance penalty.

Here are the correct MTRR entries created by uvesafb:
schlicht@netbook:~$ cat /proc/mtrr
reg00: base=0x000000000 ( 0MB), size= 2048MB, count=1: write-back
reg01: base=0x06ff00000 ( 1791MB), size= 1MB, count=1: uncachable
reg02: base=0x070000000 ( 1792MB), size= 256MB, count=1: uncachable
reg03: base=0x0d0000000 ( 3328MB), size= 16MB, count=1: write-combining

And here are the problematic PAT entries:
schlicht@netbook:~$ sudo cat /sys/kernel/debug/x86/pat_memtype_list
PAT memtype list:
write-back @ 0x0-0x1000
uncached-minus @ 0x6fedd000-0x6fee3000
uncached-minus @ 0x6fee2000-0x6fee3000
uncached-minus @ 0x6fee2000-0x6fee3000

uncached-minus @ 0xd0000000-0xd1194000 <-- created by uvesafb
uncached-minus @ 0xf4000000-0xf4009000
uncached-minus @ 0xf4200000-0xf4400000
uncached-minus @ 0xf5000000-0xf5010000
uncached-minus @ 0xf5100000-0xf5104000
uncached-minus @ 0xf5400000-0xf5404000
uncached-minus @ 0xf5404000-0xf5405000
uncached-minus @ 0xf5404000-0xf5405000
uncached-minus @ 0xfed00000-0xfed01000

Therefore I created the attached patch for uvesafb which uses ioremap_wc() to
create the correct PAT entries, as shown below:
schlicht@netbook:~$ sudo cat /sys/kernel/debug/x86/pat_memtype_list
PAT memtype list:
write-back @ 0x0-0x1000
uncached-minus @ 0x6fedd000-0x6fee3000

uncached-minus @ 0x6fee3000-0x6fee4000
uncached-minus @ 0x6fee3000-0x6fee4000
write-combining @ 0xd0000000-0xe0000000
write-combining @ 0xd0000000-0xd1194000
uncached-minus @ 0xf4000000-0xf4009000
uncached-minus @ 0xf4200000-0xf4400000
uncached-minus @ 0xf5000000-0xf5010000
uncached-minus @ 0xf5100000-0xf5104000
uncached-minus @ 0xf5400000-0xf5404000
uncached-minus @ 0xf5404000-0xf5405000
uncached-minus @ 0xf5404000-0xf5405000
uncached-minus @ 0xfed00000-0xfed01000

This results in a performance gain, objectively measurable with e.g.
x11perf -comppixwin10 -comppixwin100 -comppixwin500:
1: x11perf_xaa.log
2: x11perf_xaa_patched.log

       1                2 Operation
-------- ---------------- -----------------
124000.0 202000.0 ( 1.63) Composite 10x10 from pixmap to window
  3340.0  24400.0 ( 7.31) Composite 100x100 from pixmap to window
   131.0   1150.0 ( 8.78) Composite 500x500 from pixmap to window

You can see the serve performance gain when composing larger pixmaps to window.

The patches replace the ioremap() function with the variant matching the mtrr-
parameter. To create "write-back" PAT entries, the ioremap_cache() function
must be called after creating the MTRR entries, and the ioremap_cache() region
must completely fit into the MTRR region, this is why the MTRR region size is
now rounded up to the next power-of-two.

Since the driver will be unusable, it's better to fail the whole POST

38f7aa23c4 matroxfb: remove incorrect Matrox G200eV support
Remove incorrect Matrox G200eV support that was previously added by
commit e3a1938805

A serious issue with the incorrect G200eV support that reproduces on the
Matrox G200eV equipped IBM x3650 M2 is the total lack of text (login
banner, login prompt, etc) on the console when X is not running and
total lack of text on all of the virtual consoles after X is started.

Any concerns that the incorrect code (upstream since October 2008) has
been successfully used on non-IBM G200eV equipped system(s) appear to be
unwarranted.  In addition to the serious/non-intermittent nature of
issues that have been spotted on IBM systems, complete removal of the
incorrect code is clearly supported by the following Matrox (Yannick
Heneault) provided input:
 "It impossible that this patch should have work on a system.
 The patch only declare the G200eV as a regular G200 which is
 not case. Many registers are different, including at least the
 PLL programming sequence. If the G200eV is programmed like a
 regular G200, it will not display anything."

v1 - Initial patch that removed the incorrect code for _all_
     G200eV equipped systems.
v2 - Darrick Wong provided patch that blacklisted the incorrect
     code on G200eV equipped IBM systems leaving it enabled on
     all G200eV equipped non-IBM systems.
v3 - Same code changes included with v1 plus additional
     justification for complete removal of the incorrect code.

2de110868f OMAP: DSS2: Implement OMAP4 DSS fclk support
Add dss.dpll4_m4_ck (DSS FCLK) initialization for OMAP4. This is used
to compute the pixel clock for DPI interface and also to reconfigure
the DSS FCLK to the desired rate, corresponding to the rate computed
for pixel clock.

Adding these cpu_is_44xx() checks are meant to be temporary, until a
cleaner implementation to manage these checks are added. Currently this
is needed to get DVI display running on OMAP4 PandaBoard

0acf659f14 OMAP: DSS2: Clean up for dpll4_m4_ck handling
OMAP2 does not have dpll4_m4_ck source clock for dss functional clock,
but later OMAPs do. Currently we check for cpu type in multiple places
to find out if dpll4_m4_ck is available.

This patch cleans up dss.c by using the fact that dss.dpll4_m4_ck
pointer is NULL on OMAP2. This allows us to remove many of the cpu
checks.

1b98d7c449 ARM: pxafb: rework pxafb overlay memory management
PXAFB overlay memory management is something messy:
- it allocates memory dynamically on open/release, and it results
  in memory allocation failure after ~1h of uptime (system does not have
  115k of physically contiguous memory)
- in release callback it tries to free memory even if it was not
  allocated.

Also driver touches FDADR1 on main plane reconfiguration, and it can cause
problems if overlay1 is enabled.

This patch attempts to fix those issues.

Patch is based on Russell King's work.

53b5031430 fbdev: sh_mobile_lcdc: Add YUV framebuffer support
Supports YCbCr420sp, YCbCr422sp, and YCbCr44sp, formats
(bpp = 12, 16, and 24) respectively.

When double-buffering both Y planes appear before the C planes (Y-Y-C-C),
as opposed to  Y-C-Y-C.

Set .nonstd in struct sh_mobile_lcdc_chan_cfg to enable YUV mode, and use
.bpp to distiguish between the 3 modes.
The value of .nonstd is copied to bits 16-31 of LDDFR in the LCDC and
should be set accordingly.
.nonstd must be set to 0 for RGB mode.

Due to the encoding of YUV data, the framebuffer will clear to green
instead of black.

In YUV 420 mode, panning is only possible in 2 line increments.
Additionally in YUV 420 mode the vertical resolution of the framebuffer
must be an even number.

ea75159ee6 OMAP4: DSS2: Clock source changes for OMAP4
On OMAP3, the pixel clock for the LCD manager was derived through DISPC_FCLK as:

Lcd Pixel clock = DISPC_FCLK / lcd / pcd

Where lcd and pcd are divisors in the DISPC_DIVISOR register.

On OMAP4, the pixel clocks for LCD1 and LCD2 managers are derived from 2 new
clocks named LCD1_CLK and LCD2_CLK. The pixel clocks are calculated as:

Lcd_o Pixel clock = LCDo_CLK / lcdo /pcdo, o = 1, 2

Where lcdo and pcdo registers are divisors in DISPC_DIVISORo registers.

LCD1_CLK and LCD2_CLK can have DSS_FCLK, and the M4 divider clocks of DSI1 PLL
and DSI2 PLL as clock sources respectively. Introduce functions to select and
get the clock source for these new clocks. Modify DISPC functions get the
correct lck and pck rates based on the clock source of these clocks. Since
OMAP2/3 don't have these clocks, force OMAP2/3 to always have the LCD_CLK source
as DSS_CLK_SRC_FCK by introducing a dss feature.

Introduce clock source names for OMAP4 and some register field changes in
DSS_CTRL on OMAP4.

Currently, LCD2_CLK can only have DSS_FCLK as its clock source as DSI2 PLL
functionality hasn't been introduced yet. BUG for now if DSI2 PLL is selected as
clock.

Using dss_features to select independent core clock divider and setting

-----------------------------------------------------------------------
In OMAP4, the minimum DISPC_CORE_CLK required can be expressed as:

	DISPC_CORE_CLK >= max(PCLK1*HSCALE1, PCLK2*HSCALE2, ...)

Where PCLKi is the pixel clock generated by MANAGERi and HSCALEi is the
maximum horizontal downscaling done through MANAGERi

Based on the usecase, core clk can be increased or decreased at runtime
to save power. Such mechanism are not yet implemented. Hence, we set the
core clock divisor to 1, to support maximum range of resolutions

frequency, and the final pixel clock frequency for LCD display.

In OMAP4, there are 2 LCD channels, hence two divisor registers, DISPC_DIVISOR1
and DISPC_DIVISOR2. Also, there is a third register DISPC_DIVISOR.

The DISPC_DIVISOR in OMAP4 is used to configure lcd_div exclusively for core
functional clock configuration. For pixel clock configuration of primary and

respectively

85604b0a24 HACK: OMAP: DSS2: add delay after enabling clocks
On omap4 the registers may not be accessible right after enabling the
clocks. At some point this will be handled by pm_runtime, but, for the
time begin, adding a small delay after clk_enable() should make things
work.

f2988ab9f4 HACK: OMAP: DSS2: Fix OMAP2_DSS_USE_DSI_PLL
When using OMAP2_DSS_USE_DSI_PLL, which selects DSI PLL as source clock
for DISPC, the DSI needs the vdds_dsi regulator. Latest regulator
changes broke this, causing the the code to not acquire the regulator
when using OMAP2_DSS_USE_DSI_PLL.

This patch acquires the vdds_dsi regulator in dsi_pll_init(), fixing the
issue. This is is just a quick hack to get the OMAP2_DSS_USE_DSI_PLL
option working. There shouldn't be any other downside in this solution
than some extra lines of code.

OMAP2_DSS_USE_DSI_PLL is itself a big hack, and should be removed, and
the feature itself should be implemented in a more sane way. However,
the solution is not trivial, and people are using DSI PLL to get more
exact pixel clocks, so this hack is an acceptable temporary solution for
the time being.

bc6d4b1d3d OMAP: DSS2: Use request / release calls in Taal for DSI Virtual Channels.
Taal driver used to take a hard coded Macro for Virtual Channel and the VC_ID.
The Taal panel driver now requests for a Virtual channel through the
omap_dsi_request_vc() call in taal_probe().

The channel number returned by the request_vc() call is used for sending command
and data to the Panel. The DSI driver automatically configures the Virtual
Channel's source to either Video Port or L4 Slave port based on what the panel
driver is using it for.

The driver uses omap_dsi_release_vc() to free the VC specified by the panel.

Introduce functions which request and release VC's. This will be used in panel

omap_dsi_request_vc() takes in the pointer to the omap_dss_device, the VC_ID
parameter which goes into the header of the DSI packets, and returns a Virtual
channel number (or virtual channel register set) which it can use.

omap_dsi_set_vc_id() takes the omap_dss_device pointer, the Virtual Channel
number and the VC_ID that needs to be set for the specifed Virtual Channel.

omap_dsi_release_vc() takes the omap_dss_device pointer and the Virtual Channel
number that needs to be made free.

affe360d13 OMAP: DSS2: Have separate irq handlers for DISPC and DSI
Currently, the core DSS platform device requests for an irq line for OMAP2 and
OMAP3. Make DISPC and DSI platform devices request for a shared IRQ line.

On OMAP3, the logical OR of DSI and DISPC interrupt lines goes to the MPU. There
is a register DSS_IRQSTATUS which tells if the interrupt came from DISPC or DSI.

On OMAP2, there is no DSI, only DISPC interrupts goto the MPU. There is no
DSS_IRQSTATUS register.

Hence, it makes more sense to have separate irq handlers corresponding to the
DSS sub modules instead of having a common handler.

Since on OMAP3 the logical OR of the lines goes to MPU, the irq line is shared
among the IRQ handlers.

The hwmod irq info has been removed for DSS to DISPC and DSI for OMAP2 and OMAP3
hwmod databases. The Probes of DISPC and DSI now request for irq handlers.

When omapfb.mode is passed through bootargs, when omapfb is setting mode,

It makes use of check_timing API provided by the panel.

In current code if check_timing API is not available for attached panel,
OMAPFB would return -EINVAL and BPP sent via bootargs will not have any effect.

In case of panels like TAAL panel, omapfb or any other driver should not be allowed to
change the timings. So bpps sent via bootargs will not have an effect.

In such case we can check only the x_res and y_res with the panels resolution
and if they match go ahead and set the bpps.

However, if the board doesn't use, say, SDI, the board shouldn't need to

Currently the regulators are acquired when the DSS driver is loaded.
This means that if the kernel is configured with SDI, vdds_sdi regulator
is needed for all boards.

display of particular type is initialized. For example, vdds_sdi is
acquired when sdi_init_display() is called.

Hwmod adaptation design requires each of the DSS HW IP to be a platform driver.
So a platform_driver of DSS is created and init exit methods are moved from core.c
to its driver probe,remove. pdev member has to be maintained by its own drivers.

DSS platform driver is registered from inside omap_dss_probe, in the order desired.

8ba775ca0d OMAP2, 3: DSS2: remove forced clk-disable from omap_dss_remove
As part of omap hwmod changes, DSS will not be the only controller of its
clocks. hwmod initialization also enables the interface clocks, and
manages them.
So, when DSS is built as a module, omap_dss_remove doesn't try to disable
all clocks that have a higher usecount.

Some implementations provide an external MUX on the PL110 output to
reassign the bits to achieve 565 mode.

out what is supported by each panel and board, and therefore which
display formats are permitted.

The -rt patches change the console_semaphore to console_mutex.  As a
result, a quite large chunk of the patches changes all
acquire/release_console_sem() to acquire/release_console_mutex()

This commit makes things use more neutral function names which dont make
implications about the underlying lock.

The only real change is the return value of console_trylock which is
inverted from try_acquire_console_sem()

This patch also paves the way to switching console_sem from a semaphore to
a mutex.

5dc1365cef drivers/video/bf537-lq035.c: Add missing IS_ERR test
lcd_device_register may return ERR_PTR, so a check is added for this value
before the dereference.  All of the other changes reorganize the error
handling code in this function to avoid duplicating all of it in the added
case.

In the original code, in one case, the global variable fb_buffer was set to
NULL in error code that appears after this variable is initialized.  This
is done now in all error handling code that has this property.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r@
identifier f;
@@
f(...) { ... return ERR_PTR(...); }

@@
identifier r.f, fld;

6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

554ec37aca vgacon: check for efi machine
It seems there is a small problem of VGA palette corruption on EFI
machine.  When the kernel initializes the architecture, it checks if the
machine is a EFI machine and assumes that a VGA console can exist.

When it initializes the console in vgacon_startup it checks if it can
really use the VGA console.  I think this is where a check is missing.
Currently, the function can fail if a VESA boot mode is detected but not if
a EFI boot mode was used.

Thus vgacon_startup() doesn't fail and initialize the video card for a real
VGA mode.  This function changes the first 16entries of the VGA palette.

When the efifb driver kicks in, the palette is not restored to default
ramp value, thus the 16 first entry remain in a modified state.  The
following patch prevent this corruption.

aff5ce6ca8 drivers/video/backlight/l4f00242t03.c: fix reset sequence
The reset command is part of the init sequence and it take effect
only if the lcd is powered.

The effect of the bug was that the sequence:
set lcd power_state to FB_BLANK_POWERDOWN
set lcd power_state to FB_BLANK_UNBLANK
Did not produced a complete reboot of the LCD which was showing fuzzy
colours.

This was not experienced before implementing correctly all the LCD power
states with the patch [1].  Since before the patch [1] the regulators were
not touched and the LCD shutdown was reached with a register write.  After
the patch [1] a complete boot sequence with an initial reset is needed for
the display every time the LCD is powered up.

26bbabc8e8 drivers/video/backlight/l4f00242t03.c: prevent unbalanced calls to regulator enable/disable
Otherwise a double call to:
$ echo 4 > /sys/class/lcd/l4f00242t03/lcd_power
Will, the first power down the lcd and regulators correctly and the
second produce an unbalanced call to regulator disable.

f00117a783 video: move SH_MIPI_DSI/SH_LCD_MIPI_DSI to the top of menu
Kconfig entries SH_MIPI_DSI and SH_LCD_MIPI_DSI while being invisible to
the user, broke the FrameBuffer menu (at least in menuconfig), as they
aren't depending on respective menuconfig item (FB). In result several
items got moved to the main "Graphics support" menu. Move these two
problematic items to the top of drivers/video/Kbuild to restore nice
display of FB menu.
