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>;
        };
    };
