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

hlcdc: hlcdc@f0000000 {
bootph-all;
