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>;
			};
		};
