e020f9af6d OMAP: DSS2: remove sub-panel system
The system to allow panel drivers to exists as attached to ctrl drivers
did never work very well. It is not useed, and this patch removes it to
make the driver cleaner.

For now, controller drivers need to include also the panel driver code. In
the future a proper mechanism for this should be developed, perhaps by
creating busses for controllers.

e296264977 OMAP: DSS2: Check ctx loss count only when starting the first clock
When OMAP PM layer is no-op/debug, the PM layer will increment context
loss count with every call. This resulted DSS2 to restore context
whenever a clock was enabled.

This commit checks the context loss count only when the context actually
could have been lost, ie. when enabling a clock when no clocks had been
previously enabled.

dd8079d6a9 OMAP: DSS2: DSI: configure all DSI VCs
Instead of configuring only VC0 to be usable, configure all four VCs
similarly. This is needed to utilize the other VCs.

Setting the FIFO sizes evenly for all VCs, regardless of how many VCs are
actually used, is not optimal. However, this affects only cases when
larger amounts of data are written or read via L4, meaning that normal use
cases are not affected.

At some point this could be optimized better to suit different use cases.

2f18c4d898 OMAP: DSS2: improve DSS clk src selection
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.

8a2cfea8cc OMAP: DSS2: enable VDDS_DSI when using DPI
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.

e721032785 omapfb: lcd_ams_delta: add support for contrast control
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,

3e9ff04408 omapfb: Fix 12-bit display (RGB444 color mode) handling
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.
