A simple DRM/KMS driver for the TI LCD Controller found in various
smaller TI parts (AM33xx, OMAPL138, etc). This driver uses the
CMA helpers. Currently only the TFP410 DVI encoder is supported
(tested with beaglebone + DVI cape). There are also various LCD
displays, for which support can be added (as I get hw to test on),
and an external i2c HDMI encoder found on some boards.
The display controller supports a single CRTC. And the encoder+
connector are split out into sub-devices. Depending on which LCD
or external encoder is actually present, the appropriate output
module(s) will be loaded.
v1: original
v2: fix fb refcnting and few other cleanups
v3: get +/- vsync/hsync from timings rather than panel-info, add
option DT max-bandwidth field so driver doesn't attempt to
pick a display mode with too high memory bandwidth, and other
small cleanups
v4: remove some unneeded stuff from panel-info struct, properly
set high bits for hfp/hsw/hbp for rev 2, add DT bindings docs

Choose this option if you have an TI SoC with LCDC display

controller, for example AM33xx in beagle-bone, DA8xx, or

OMAP-L1xx. This driver replaces the FB_DA8XX fbdev driver.
