| 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. |
