-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:
-
-	fb@d8050800 {
-		compatible = "via,vt8500-fb";
-		reg = <0xd800e400 0x400>;
-		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>;
-				hsync-len = <0>;
-				vback-porch = <32>;
-				vfront-porch = <11>;
-				vsync-len = <1>;
-			};
-		};
