From: Paul Boddie <paul@xxxxxxxxxxxxx> Add support for the LCD controller present on JZ4780 SoCs. This SoC uses 8-byte descriptors which extend the current 4-byte descriptors used for other Ingenic SoCs. Note that plane f0 is not working and disabled to be seen from user-space. Tested on MIPS Creator CI20 board. Signed-off-by: Paul Boddie <paul@xxxxxxxxxxxxx> Signed-off-by: Ezequiel Garcia <ezequiel@xxxxxxxxxxxxx> Signed-off-by: H.
