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>;
};
};
};
