   1 Atmel HLCDC Framebuffer
   2 -----------------------------------------------------
   3 Required properties:
   4 - compatible :
   5         "atmel,sama5d2-hlcdc", "atmel,at91sam9x5-hlcdc".
   6 - reg: physical base address of the controller and length of memory mapped
   7        region.
   8 - clocks: phandles to input clocks.
   9 - atmel,vl-bpix: Bits per pixel.
  10 - atmel,output-mode: LCD Controller Output Mode,
  11   The unit is bits per pixel, there are four values,
  12   <12>, <16>, <18>, <24>, the default value is <24>.
  13 - atmel,guard-time: lcd guard time (Delay in frame periods).
  14 - display-timings: please refer the displaymode.txt.
