Move the panel/encoder driver compatible-string converter from
arch/arm/mach-omap2/display.c to omapdss driver. That is a more logical
place for it, as it's really an omapdss internal hack.

The code is rewritten to follow the video node graph, starting from
omapdss. This removes the need to have the device compatible-string
database.

This adds a new driver to omapdss for OMAP5 HDMI. However, the new
driver uses common HDMI files which are shared with OMAP4 HDMI driver.

OMAP5 HDMI has a different HDMI core IP compared to OMAP4, but has very
similar PLL and PHY IPs which can be handled with common code.

We'll soon add support for OMAP5 HDMI, which uses some of the same files
as OMAP4 HDMI does.

This patch adds a new config entry "OMAP2_DSS_HDMI_COMMON", which both
OMAP4 and OMAP5 HDMI config entries can select. OMAP2_DSS_HDMI_COMMON
will cause the common HDMI files to be compiled.

The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.

Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.

No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.

OMAPDSS's RFBI encoder driver has not been working for some time. The
Nokia N800 is the only board in the mainline that uses RFBI, but it has
never been fully functional.

The RFBI driver needs to be updated to the new panel model, but as
the driver is rather unmaintained and there's no way to test the
changes, let's mark the driver as broken.

Add helper functions to convert between omapdss specific video timings
and the common videomode.

Eventually omapdss will be changed to use only the common video timings,
and these helper functions will make the transition easier.

The config option CONFIG_OMAP2_DSS_DEBUG_SUPPORT has been removed and replaced
with CONFIG_OMAP2_DSS_DEBUG and CONFIG_OMAP2_DSS_DEBUGFS. CONFIG_OMAP2_DSS_DEBUG

OMAPDSS. Both the config options are disabled by default and can be enabled
independently of one another as per convenience.

Fake VSYNC support is a hack and has some bugs in it. It isn't used by any user
of DSS. Remove Fake VSYNC support. For DSI command mode and RFBI panels, a user

For some unknown reason we may get SYNC_LOST errors from the display
subsystem at initialization time if we don't sleep before resetting the
DSS. See the source (dss.c) for more comments.

However, 50ms is quite long time to sleep, and with some configurations
the SYNC_LOST may never happen, so this patch creates a Kconfig option
to disable the sleep.

without the rest of the core commits. This shouldn't be a problem, as no
