Pointed out by Lucas who found the new one in a comment in
setup_percpu.c. And then I fixed the others that I grepped
for.

032093bd44 drivers/video/nuc900fb.c: fix lcd build error
Fix a nuc900 lcd build error.

Since the 'nuc900_driver_clksrc_div()' API cannot be merged into mainline
successfully, I removed this clock source selection hook in this driver.
This means nuc900 lcd driver has to select default clock source from the
external crystal now.

256a804283 OMAPFB: LCDC: change update_mode to DISABLED when going suspend
I was observing the following error messages on my OMAP1 based Amstrad Delta
board when first changing from text to graphics mode or vice versa after the
LCD display had been blanked:
	omapfb omapfb: timeout waiting for FRAME DONE
with a followup error message while unblanking it back:
	omapfb omapfb: resetting (status 0xffffffb2,reset count 1)
As a visible result, image pixels happened to be shifted by a few bits,
giving wrong colors.

Examining the code, I found that this problem occures when an OMAP1 internal
LCD controller is disabled from omap_lcdc_suspend() and then a subsequent
omap_lcdc_setup_plane() calls disable_controller() again. This potentially
error provoking behaviour is triggered by the lcdc.update_mode flag being kept
at OMAP_AUTO_UPDATE, regardless of the controller and panel being suspended.

This patch tries to correct the problem by replacing both omap_lcdc_suspend()
and omap_lcdc_resume() function bodies with single calls to
omap_lcdc_set_update_mode() with a respective OMAP_UPDATE_DISABLE or
OMAP_AUTO_UPDATE argument. As a result, exactly the same lower level
operations are performed, with addition of changing the lcdc.update_mode flag
to a value better suited for the controller state. This prevents any further
calls to disable_controller() from omap_lcdc_setup_plane() while the display
is suspended.

Created against linux-2.6.34-rc7.
Tested on Amstrad Delta.

b1413357d9 fbdev: fix frame buffer devices menu
Commit f601441916 ("imxfb: add support for
i.MX25:) has inserted the symbol HAVE_FB_IMX, which does not depend on FB
after the menuconfig FB.  This breaks the menu, presenting most of the
drivers outside of it, when using menuconfig.

Moving the symbol to the start of the file, just like HAVE_FB_ATMEL, fixes
the problem without breaking it for iMX25 configurations (tested with
ARCH=arm, no build).

fbae3fb154 i2c: Remove all i2c_set_clientdata(client, NULL) in drivers
I2C drivers can use the clientdata-pointer to point to private data. As I2C
devices are not really unregistered, but merely detached from their driver, it
used to be the drivers obligation to clear this pointer during remove() or a
failed probe(). As a couple of drivers forgot to do this, it was agreed that it
was cleaner if the i2c-core does this clearance when appropriate, as there is
no guarantee for the lifetime of the clientdata-pointer after remove() anyhow.
This feature was added to the core with commit
e4a7b9b04d to fix the faulty drivers.

As there is no need anymore to clear the clientdata-pointer, remove all current
occurrences in the drivers to simplify the code and prevent confusion.

ee378a5c65 backlight: add S6E63M0 AMOLED LCD Panel driver
This is S6E63M0 AMOLED LCD Panel(480x800) driver using 3-wired SPI
interface also almost features for lcd panel driver has been implemented
in here.  and I added new structure common for all the lcd panel drivers
to include/linux/lcd.h file.

LCD Panel driver needs interfaces for controlling device power such as
power on/off and reset.  these interfaces are device specific so it should
be implemented to machine code at this time, we should create new
structure for registering these functions as callbacks and also a header
file for that structure and finally registered callback functions would be
called by lcd panel driver.  such header file(including new structure for
lcd panel) would be added for all the lcd panel drivers.

If anyone provides common structure for registering such callback
functions then we could reduce unnecessary header files for lcd panel.  I
thought that suitable anyone could be include/linux/lcd.h so a new
lcd_platform_data structure was added there.

Cleanup the "depends on" logic by wrapping the affected config options in

Remove all the "default n" since that is the default default.

49bbd815fd fb_defio: fix for non-dirty ptes
Fix a problem observed while using fb_defio with a short delay on a
PowerPC platform.

It is possible that page_mkclean() is invoked in the deferred io work
function _before_ a PTE has been marked dirty.  In this case, the page is
removed from the defio pagelist but page_mkclean() does not write-protect
the page again.  The end result is that defio ignores all subsequent
writes to the page and the corresponding portions of the framebuffer never
get updated.

The fix consists in keeping track of the pages with non-dirty PTEs,
re-checking them again on the next deferred io work iteration.  Note that
those pages are not passed to the defio callback as they are not written
by userspace yet.

Also the drivers remove routine should be moved from .text to .devexit.text

FBIO_WAITFORVSYNC is currently implemented by matroxfb, atyfb, intelfb and

defines.

1f9c3e1f07 fbdev: da8xx/omap-l1xx: implement double buffering
This work includes the following:

- Implement handler for FBIO_WAITFORVSYNC ioctl.

- Allocate the data and palette buffers separately.  A consequence of
  this is that the palette and data loading is now done in different
  phases.  And that the LCD must be disabled temporarily after the palette
  is loaded but this will only happen once after init and each time the
  palette is changed.  I think this is OK.

- Allocate two (ping and pong) framebuffers from memory.

- Add pan_display handler which toggles the LCDC DMA registers between
  the ping and pong buffers.
