9e6866d3b6 tegra: video: Convert tegra20 LCD driver to driver model
Move this driver over to use driver model. This involves rearranging the
code somewhat. The effect is that everything is run from the probe() method.

Boards which use this are fixed up, but only seaboard is tested.

ce0c474a72 tegra: video: Merge the two config structures together
We have a structure for the display panel and another for the controller.
There is some overlap between them. Merge them to simplify the driver.

71cafc3fba tegra: video: Merge the display driver into one file
At present we have code in arch/arm and code in drivers/video. Move it all
into drivers/video since it is a display driver and our current approach is
to put all driver code in drivers/.

Make a few functions static now that they are not used outside the file.

0f9258228e of: clean up OF_CONTROL ifdef conditionals
We have flipped CONFIG_SPL_DISABLE_OF_CONTROL.  We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:

 #ifdef CONFIG_OF_CONTROL
 # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
 #  define OF_CONTROL 0
 # else
 #  define OF_CONTROL 1
 # endif
 #else
 # define OF_CONTROL 0
 #endif

Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute.  It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.

Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.

70ad375ee4 ARM: tegra: Tegra20 pinmux cleanup
This renames all the Tegra20 pinmux pins and functions so they have a
prefix which matches the type name.

The entries in tegra20_pingroups[] are all updated to remove the columns
which are no longer used.

All affected code is updated to match.

46d1d5dd43 common/lcd.c: cleanup use of global variables
lcd_color_fg and lcd_color_bg had to be declared in board specific
code, but were not actually used there; in addition, we have getter /
setter functions for these, which were not used either.

Get rid of the global variables, and use the getter function where
needed (so far no setter calls are needed).

0c5587549b video: tegra: Update line length to match resolution
Instead of storing the computed line length in a local variable, store
it in the global lcd_line_length variable to make sure the LCD subsystem
can properly draw content for the display resolution.

This probably wasn't noticed yet because the only board where LCD
support is currently enabled is Seaboard, which runs at a 1366x768
resolution. As it happens this is the maximum resolution supported and
also the default that is used to initialize the framebuffer before the
configuration from DT is available.
