e3a411a3df [SPARC64]: Fix of_iounmap() region release.
We need to pass in the resource otherwise we cannot
release the region properly.  We must know whether it is
an I/O or MEM resource.

31fccf7fe4 [PATCH] gxt4500: Fix colormap and PLL setting, support GXT6000P
This fixes some bugs in the gxt4500 framebuffer driver, and adds support
for GXT6000P cards.

First, I had the red and blue channels swapped in the colormap update code,
resulting in penguins' noses and feet turning blue (though the penguins
weren't actually shivering :).

Secondly, the code that calculated the values to put in the PLL that
generates the pixel clock wasn't observing some constraints that I wasn't
originally aware of, but am now that I have some documentation on the chip.

The GXT6000P is essentially identical from software's point of view, except
for a different reference clock for the PLL, and the addition of a geometry
engine (which this driver doesn't use).

519ab5f2be ACPI: video: Add dev argument for backlight_device_register
This patch set adds generic abstract layer support for acpi video driver to
have generic user interface to control backlight and output switch control by
leveraging the existing backlight sysfs class driver, and by adding a new
video output sysfs class driver.

This patch:

Add dev argument for backlight_device_register to link the class device to
real device object.  The platform specific driver should find a way to get the
real device object for their video device.

	  echo "De-casting $f..."
	  perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f

And then go through and reinstate those cases where code is casting pointers
to non-pointers.

And then drop a few hunks which conflicted with outstanding work.

4437cd1e98 [PATCH] backlight: do not power off backlight when unregistering
ACPI drivers like ibm-acpi are moving to the backlight sysfs
infrastructure.  During ibm-acpi testing, I have noticed that
backlight_device_unregister() sets the display brightness and power to
zero.

This causes the display to be dimmed on ibm-acpi module removal.  It will
affect all other ACPI drivers that are being converted to use the backlight
class, as well.  It also affects a number of framebuffer devices that are
used on desktops and laptops which might also not want such behaviour.

Since working around this behaviour requires undesireable hacks, Richard
Purdie decided that we would be better off reverting the changes in the
sysfs class, and adding the code to dim and power off the backlight device
to the drivers that want it.  This patch is my attempt to do so.

Patch against latest linux-2.6.git.  Changes untested, as I lack the
required hardware.  Still, they are trivial enough that, apart from typos,
there is little chance of getting them wrong.

024cd7e088 [PATCH] softcursor.c: avoid unaligned accesses
Fix some possible unaligned accesses when accessing fields of 'image'
pointer.  Indeed this pointer was obtained by allocating a block of memory
that embeds a temporary array plus an image structure.  The temporary
buffer was located at the start of the allocated block and depending on its
size, the image structure which comes right after can be unaligned.

For example when using mini fonts (4x6) (cursor's width is 4 and its height
is 6) the temporary buf size is 6 bytes.

Therefore this patch moves the image structure to the start of the block
and moves the temporary buffer right after.  It makes 'image' pointer
always aligned and since the tempo buf is a buffer of char, it's always
correctly aligned as well.

It also fixes the file header alignement.

ea465250d4 [PATCH] mbxfb: Add YUV video overlay support
This patch adds a way to create and use the video plane (YUV overlay) and
scaling video scaling features of the chip.

The overlay is configured, resized and modified using a device specific

  - If no platform data was passed, print an error and exit instead of crashing.
  - Added a write_reg(_dly) macro. This improves readability when
    manipulating chip registers. (no more udelay() after each write).
  - Comments about some issues.

128806c3b3 [PATCH] mbxfb: add more registers to debugfs
This patch fixes debugfs for mbxfb and adds some missing registers.

The way registers were read was out of sync with the rest of the driver (direct
access instead of using readl())

sdram controller registers are now accessible in the sdram/ subdirectory and
some other registers are grouped in the misc/ subdirectory.

03ae4e0ccc [PATCH] au11oofb: fix to remove flickering
Currently a lot of flickering is seen on the VGA and LCD port when one
starts a DBAu1100 board, with 'CONFIG_PRINTK=3Dy'.

This patch removes the flickering and as a result all kernel messages come
by in a nice steady fashion.

357b819dda [PATCH] s3c2410fb: Add support for STN displays
This patch adds support for stn displays on the s3c2410 arm SoC.

The LCD type is choosen by a new field in the s3c2410fb_mach_info structure
and its value is the value of the PNRMODE bits.  This worth to be noted as
a value of 0 means that you configure a 4 bit dual scan stn display.
