+-----------------------------------------------------
+
+Required properties:
+- compatible : "wm,wm8505-fb"
+- reg : Should contain 1 register ranges(address and length)
+- bits-per-pixel : bit depth of framebuffer (16 or 32)
+
+Required subnodes:
+- display-timings: see display-timing.txt for information
+
+Example:
