-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>;
