+VIA VT8500 Framebuffer
+-----------------------------------------------------
+
+Required properties:
+- compatible : "via,vt8500-fb"
+- reg : Should contain 1 register ranges(address and length)
+- interrupts : framebuffer controller interrupt
+- bits-per-pixel : bit depth of framebuffer (16 or 32)
+
+Required subnodes:
+- display-timings: see display-timing.txt for information
+
+Example:
+

+ interrupts = <12>;
+ bits-per-pixel = <16>;
+
+ display-timings {
+ native-mode = <&timing0>;
+ timing0: 800x480 {
+ clock-frequency = <0>; /* unused but required */
+ hactive = <800>;
+ vactive = <480>;
+ hfront-porch = <40>;
+ hback-porch = <88>;
