The patch extends the Amstrad Delta LCD panel driver with optional support for
changing contrast using standard LCD class device API instead of setting it
silently to a default value at panel enable. It also allows for lowering power
consumption by turning off OMAP_PWL_CLK_ENABLE via lcd_ops.set_power callback.
Created and tested against linux-omap for-next,
commit 155a75d9725e66e5ec8a383822957dee52427057.

Support for RGB444 (12-bit) pixel format has been introduced into omapfb/lcdc
by Mark Underwood on 2006-05-26 (commit
f74edb6668aad9fc8e81585861b18f996c78a574) in preparation for Amstrad Delta
(E3) videophone LCD display support.
Before the Amstrad Delta LCD patch by Jonathan McDowell was applied (on
2006-08-04, commit 8d22fb2ea004cdb6379b54c1a8fd1546cfe40ed7), omapfb and lcdc
code was changed substantially (commit
e563dc81aa01bd8bbb01bc53975a15c398715f62 dated 2006-06-26) in a way that broke
Mark's 12-bit display support. Than, a patch by Jonathan, that supposed to
correct the problem, was introduced immediatelly (on 2006-08-04, commit
e10a75b49e7a57ae17c28b705153c70eba15a8ef).
As a result, the Amstrad Delta display was working correctly at boot time,
with fbset reporting:
geometry 480 320 480 320 16
...
rgba 4/8,4/4,4/0,0/0
However, after first framebuffer reinitialization, colors were no longer being
displayed correctly and fbset was reporting:
rgba 5/11,6/5,5/0,0/0
The patch tries to correct the issue by setting plane->color_mode depending on
panel->bpp, not var->bits_per_pixel.
Created and tested on Amstrad Delta against linux-2.6.33-rc3.

If the panel's probe had failed, omapfb would still go on, eventually
crashing.
A better fix would be to handle each display properly, and leaving just
the failed display out. But that is a bigger change.

The intelfb driver sets color map depending on currently active pipe.
However, if an LVDS display is attached (like in laptop) the active pipe
variable is never set. The default value is PIPE_A and can be wrong. Set
up the pipe variable during driver initialization after hardware state was
read.
Also, the detection of the active display (and hence the pipe) is wrong.
The pipes are assigned to so called planes. Both pipes are always enabled
on my laptop but only one plane is enabled (the plane A for the CRT or the
plane B for the LVDS). Change active pipe detection code to take into
account a status of the plane assigned to each pipe.
The problem is visible in the 8 bpp mode if colors above 15 are used. The
first 16 color entries are displayed correctly.
The graphics chip description is here (G45 vol. 3):

Regression caused in 2.6.23 and then despite repeated requests never fixed
or dealt with (Petr promised to sort it in 2008 but seems to have
forgotten).
Enough is enough - remove the problem line that was added. If it upsets
someone they've had two years to deal with it and at the very least it'll
rattle their cage and wake them up.
