One of the compatible panels is a 7" 800x480 RGB panel from Bananapi. The backlight can be controlled by driving a PWM signal from the SoC at different duty cycles. The LCD enable pin does not seem to do anything, but it is nevertheless included for completeness. There is also a FT5306 capacitive touchscreen controller. This should not be confused with the other 7" LCD that is LVDS based and has a resolution of 1024x600. This patch enables all of the above for the BPI-M1+.
