Also adds comments on how to get support 24 bit RGB mode. After this patch am335x-boneblack support RGB565, BGR888, and XBGR8888 color formats. See details in Documentation/devicetree/bindings/display/tilcdc/tilcdc.txt. The BBB has straight color wiring from am335x to tda19988, however the tda19988 can be configured to cross the blue and red wires. The comments show how to do that with video-ports property of tda19988 node and how to tell LCDC that blue and red wires are crossed, with blue-and-red-wiring LCDC node property. This changes supported color formats from 16 bit RGB and 24 bit BGR to 16 bit BGR and 24 bit RGB. Signed-off-by: Jyri Sarha Reviewed-by: Tomi Valkeinen --- Hi Tony, Could you pick this for 4.10. We left it out form 4.9 to avoid conflict with beaglebone-back hdmi audio dts patches that slipped in trough drm branch.
