Boards can pass display timing info for drivers using EDID block. Provide common function to add board specific EDID data to the device tree. Subsequent patch makes use of this functionality. Detailed timing descriptor data from EDID is used for programming the display controller. This is currently implemented on the Linux side by the fsl-diu-fb frame buffer driver and it is documented there in Documentation/powerpc/dts-bindings/fsl/diu.txt.
