Currently, it is possible to set a graphics VESA mode at boot time via the
vga= parameter even when no framebuffer driver supporting this is
configured. This could lead to the system booting with a black screen,
without a usable console.
Fix this problem by only allowing to set graphics modes at boot time if a
supporting framebuffer driver is configured.

Implement support for HW color expansion of 1bpp images, along with some
improvements to the FIFO handling and other accel operations.
The offset fixup code is now unnecessary as the fbcon core will call our
set_par upon switch back from KD_GRAPHICS before anything else happens. I
removed it as it would slow down accel operations.
The fifo wait has been improved to avoid hitting the HW register as often,
and the various accel ops are now performing better caching of register
values.
Overall, this improve accel performances. The imageblit acceleration does
result in a small overall regression in performances on some machines (on
the order of 5% on some x86), probably becaus the SW path provides a
better bus utilisation, but I decided to ingnore that as the performances
is still very good, and on the other hand, some machines such as some
sparc64 get a 3 fold performance improvement.

A memory clock value (MCLK) is changed to a minimum required by a current
mode bandwidth. This usually lowers the MCLK to its minimum (50 MHz) thus
decreasing the card performance. Just leave the MCLK value set by card
BIOS.
The CL-GD5446 Technical Reference Manual point 9.9.1.3 states that if a
pixclock value is close (~1%) to the MCLK or MCLK/2 this may result in a
jitter on the screen. A countermeasure is to use the MCLK as pixclock
source instead of a VCLK. The patch implements this as well.

Add support for Intel's 945GME graphics chip to the intelfb driver. I
have assumed that the 945GME is identical to the already-supported 945GM
apart from its PCI IDs; this is based on a quick look at the X driver for
these chips which seems to treat them identically.
The 945GME is used in the ASUS Eee 901, and I coded this in the hope that
I'd be able to use it to get a console at the native 1024x600 resolution
which is not known to the BIOS. I realised too late that the intelfb
driver does not support mode changing on laptops, so it won't be any
use for me.

This updates most of the OMAP drivers which are in mainline to switch to
using the cross-platform GPIO calls instead of the older OMAP-specific
ones.
This is all fairly brainless/obvious stuff. Probably the most interesting
bit is to observe that the omap-keypad code seems to now have a portable
core that could work with non-OMAP matrix keypads. (That would improve
with hardware IRQ debouncing enabled, of course...)

This provides a workaround for users of sh_mobile_lcdcfb that don't
define HAVE_CLK and have otherwise sane clock initialization.
At the same time, move the sh_mobile_lcdc.h header to include/video/.

This type of LCD panel can be found on PXA3xx/Littleton platforms.
Add LCD device and SPI-based driver for this.

This is not generic enough, added here for backward compatibility.
And make this an individual commit so future revert will be a bit
easier.

The driver is based on different source files including corgi_ssp.c,
corgi_lcd.c and corgi_bl.c, previously authored by Richard Purdie
and many others.
The LCD and Backlight device actually share the same SPI device, so
they are made into this single driver.

Some LCD panels are capable of different resolutions, and is allowed
to change at run-time, so to make "struct lcd_device" to be able to
handle mode change events here.

When suspending the system with atmel_lcdfb enabled, I sometimes see
this:
atmel_lcdfb atmel_lcdfb.0: FIFO underflow 0x10
Which can be explained by the fact that we're not stopping the LCD
controller and its DMA engine when suspending, we're just gating the
clocks to them.
There's another potential issue which may be harder to trigger but
much more nasty: If we gate the clocks at _just_ the right moment,
e.g. when the DMA engine is doing a bus transaction, we may cause the
DMA engine to violate the system bus protocol and cause a lockup.
Avoid these issues by shutting down the LCD controller before entering
suspend (and restarting it when resuming). This prevents the underrun
from happening in the first place, and prevents whatever nastiness is
happening when the bus clock stops in the middle of a DMA transfer.

OMAP1_IO_ADDRESS(), OMAP2_IO_ADDRESS() and IO_ADDRESS() returns cookies
for use with __raw_{read|write}* for accessing registers. Therefore,
these macros should return (void __iomem *) cookies, not integer values.
Doing this improves typechecking, and means we can find those places
where, eg, DMA controllers are incorrectly given virtual addresses to
DMA to, or physical addresses are thrown through a virtual to physical
address translation.

Impact: cleanup
Video mode selection became always possible in 2.6.23-rc1 after i386 setup
code rewrite in C.
Regardless, VIDEO_SELECT is stupid config option because it affects only
kernel setup code, not code which always stays in memory.
vga= always possible now which is good.

1. Check if virtual resolution fits into memory.
Otherwise, Linux hangs during panning.
2. When selected use all available memory to
maximize yres_virtual to speed up panning
(previously also xres_virtual was increased).
3. Simplify memory restriction calculations.

The original am200epd driver was designed with bad assumptions. It
manipulated GPSR/GPLR registers directly. It relied on direct access to the
pxa LCDC registers which have since conflicted with commit
ce4fb7b892 . This patch moves it into mach-pxa
and overhauls it to use a fb obtained through fb notifiers. It now uses the
generic GPIO api.

These changes are used in order to support the use of the framebuffer
provided by the platform device driver rather than to directly allocate one.
Other changes are cleanup to error handling and order of release.
