the new_regs stuff has been removed, and all the setup (modification to those
fbi->reg_*) is protected with IRQ disabled
* disable IRQ is too heavy here, provided that no IRQ context will
touch the fbi->reg_* and the only possible contending place is
in the CPUFREQ_POSTCHANGE (task context), a mutex will be better,
leave this for future improvement

Reasons:
1. straight forward: the name "LCD_COLOR_DSTN_16BPP" is much better
than "LCCR0_Pas | LCCR0_Color | LCCR0_Dual"
2. by defining LCD connection types as constants, it allows only
valid possibilities
3. by removing the dependency of register bits definitions, those
can be later moved into the body of pxafb.c, instead of having
a regs-lcd.h around
Currently, only lubbock, mainstone, zylonite and littleton have been
modified to support these types (see coming patches after this).
Other platforms are encouraged to change their way describing the
LCD controller connections.

This is part of the effort moving peripheral registers outside of pxa-regs.h,
and using ioremap() make it possible the same IP can be re-used on different
processors with different registers space
As a result, the fixed mapping in pxa_map_io() is removed.
The regs-lcd.h can actually moved to where closer to pxafb.c but some of its
bit definitions are directly used by various platform code, though this is not
a good style.

pxafb_parse_options() has very long lines exceeding far beyond 80 characters,
which makes the function looks bad. Un-nest it into smaller functions and use
a temporary string for only what has been overridden instead of the whole
dev_info() message to reduce the line a bit more.

A command that causes a line feed while a background color is active,
such as
perl -e 'print "x" x 60, "\e[44m", "x" x 40, "\e[0m\n"'
and
perl -e 'print "x" x 40, "\e[44m\n", "x" x 40, "\e[0m\n"'
causes the line that was started as a result of the line feed to be completely
filled with the currently active background color instead of the default
color.
When scrolling, part of the current screen is memcpy'd/memmove'd to the new
region, and the new line(s) that will appear as a result are cleared using
memset. However, the lines are cleared with vc->vc_video_erase_char, causing
them to be colored with the currently active background color. This is
different from X11 terminal emulators which always paint the new lines with
the default background color (e.g. `xterm -bg black`).
The clear operation (\e[1J and \e[2J) also use vc_video_erase_char, so a new
vc->vc_scrl_erase_char is introduced with contains the erase character used
for scrolling, which is built from vc->vc_def_color instead of vc->vc_color.

965G/965GM
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.

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 AOIs
All /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/fb0
required 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@60
Bpp
bpp=32, bpp=24, or bpp=16
Monitor
monitor=0, monitor=1, monitor=2
0 is DVI
1 is Single link LVDS
2 is Double link LVDS
Note: 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.)

- lx_powerup and lx_powerdown functions which restore/save registers and
enable/disable graphic engines.
- lxfb_suspend/lxfb_resume

- 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.

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).

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...

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.
