dss_select_clk_source() was rather confusing. Selecting the source with
enums is much clearer.

The clk source selection is also stored into memory, so that we know what
is the selected source, even when clocks are off. This is important during
setup, as we need to what clocks to turn on before the clocks are turned
on.

The regulator is now enabled by DSS driver, and thus the panel driver
doesn't need to touch it.
Signed-off-by: NTomi Valkeinen <tomi.valkeinen@nokia.com>

It looks like on OMAP3 some DSS pins need VDDS_DSI to function properly.

This has not been confirmed from TI, but looking at figure 15-1 "Display
subsystem highlight" from the TRM, some data pins come near the DSI and SDI
blocks. This is not very hard evidence, but the fact remains that with the
power on, pixels are ok, and with the power off, pixels are not ok.

It may also be that VDDS_SDI is needed to power some pins, but as normally
both VDDS_SDI and VDDS_DSI come from the same power source, this hasn't
been shown.

It seems that a single driver can only get a regulator once. This patch
solves it by getting all the required regulators in one place, and from
which the submodules then get the regulators they need.

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.

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

A better fix would be to handle each display properly, and leaving just
the failed display out. But that is a bigger change.
