Add support for the 965G and 965GM graphic chipsets to the intelfb driver. I
have a notebook with an Intel Mobile GM965/GL960 Integrated Graphics
Controller and with the attached patch the framebuffer comes up. I have
tested it a bit with DirectFB to make sure it is working stable.I also have an Intel Mobile GM945 and I compared the results, the programming
interface of the 9xx series from Intel is mostly the same, so I think the
patch should add all the functionality which the 945GM has.Signed-off-by: Maik Broemme

Note: looks like accesses to "registered_fb" are done without any exclusion
so there're none in new proc code, too. This should be fixed in separate
patch.[akpm@linux-foundation.org: coding-style fixes]

The following features are supported:
plane 0 works as a regular frame buffer, can be accessed by /dev/fb0
plane 1 has two AOIs (area of interest), can be accessed by /dev/fb1 and /dev/fb2
plane 2 has two AOIs, can be accessed by /dev/fb3 and /dev/fb4
Special ioctls support AOIsAll /dev/fb* can be used as regular frame buffer devices, except hardware
change can only be made through /dev/fb0. Changing pixel clock has no effect
on other fbs.Limitation of usage of AOIs:
AOIs on the same plane can not be horizonally overlapped
AOIs have horizonal order, i.e. AOI0 should be always on top of AOI1
AOIs can not beyond phisical display area. Application should check AOI geometry
before changing physical resolution on /dev/fb0required command line parameters to preallocate memory for frame buffer diufb.
optional command line parameters to set modes and monitor
video=fslfb:[resolution][,bpp][,monitor]
Syntax:Resolution
xres x yres-bpp@refresh_rate, the -bpp and @refresh_rate are optional
eg, 1024x768, 1280x1024, 1280x1024-32, 1280x1024@60, 1280x1024-32@60, 1280x480-32@60Bpp
bpp=32, bpp=24, or bpp=16Monitor
monitor=0, monitor=1, monitor=2
0 is DVI
1 is Single link LVDS
2 is Double link LVDSNote: switching monitor is a board feather, not DIU feather. MPC8610HPCD has three
monitor ports to swtich to. MPC5121ADS doesn't have additional monitor port. So switching
monirot port for MPC5121ADS has no effect.If compiled as a module, it takes pamameters mode, bpp, monitor with the same syntax above.

Since there's no way to autodetect panel modes, we're forced to hardcode them
in the driver and add a big fat #ifdef. The OLPC DCON needs a specific mode
line (at 1200x900). This adds it to both gxfb and lxfb.(Jordan said: We could probably detect the panel mode, but there isn't any
reason to since the panel timings are well known and won't change. While OFW
detection would be good computer science fu, it would be a wasted effort since
its so easy to hard code them into the table.)Signed-off-by: Andres Salomon

This adds the ability to suspend/resume the lxfb driver, which includes:
- Register and palette saving code; registers are stored in lxfb_par.
A few MSR values are saved as well.
- lx_powerup and lx_powerdown functions which restore/save registers and
enable/disable graphic engines.
- lxfb_suspend/lxfb_resumeOriginally based on a patch by Jordan Crouse.

- Rename various bitfield defines to match the data sheet names.
- Rename DF_ register definitions to VP_ to match the data sheet;
ie, DF_PAR -> VP_PAR.
- for GP/DC registers, rather than defining to specific addresses, use
an enum to number them sequentially and just multiply by 4 (bytes) to
access them (in read_*/write_* functions).
- for VP/FP registers, use an enum and multiple by 8 (bytes). They're
64bit registers.Signed-off-by: Andres Salomon

Adds different wiring mode for the LCD screen.
The legacy atmel LCDC IP uses a non standard color mode, "BGR-555.1" instead
"RGB-565". The major part of graphic stacks for embedded systems uses only
"RGB-565". It is possible to swap LCD IOs instead of doing this bit swapping
by software (See application note AT91SAM9 LCD Controller
http://www.atmel.com/dyn/resources/prod_documents/doc6300.pdf)This wire swapping is done on the at91sam9rl-ek board (board code
using this patch will come later).Signed-off-by: Nicolas Ferre

Teach atmel_lcdfb driver how to suspend/resume.
Note that the backlight control should probably do more of the same stuff:
turning off display power (more than just the backlight) and stopping the
clocks (and dma to drive the no-longer-seen display). No point in wasting
power to generate images that can't be observed, after all...Signed-off-by: David Brownell

If the user specified a fixed framebuffer address on the command line, it may
have been initialized already with a splash image or something, so we
shouldn't clear it.Therefore, we should only initialize the framebuffer if we allocated it
ourselves. This patch also updates the AVR32 setup code to clear the
framebuffer if it allocated it itself, i.e. the user didn't provide a fixed
address or the reservation failed.I've updated the at91 platform code as well so that it initializes the
framebuffer if it is located in SRAM, but I haven't tested that it actually
works.Signed-off-by: Haavard Skinnemoen

Don't treat valid modes returned by fb_find_mode() (best-fit modes, default
modes or the first valid mode) as errors.Currently, when fb_find_mode() finds a valid mode belonging to one of the
above-mentioned classes, uvesafb will ignore it and will try to set a 640x480

the valid mode returned by fb_find_mode() instead.Signed-off-by: Michal Januszewski
