1Mediatek DPI Device
2===================
3
4The Mediatek DPI function block is a sink of the display subsystem and
5provides 8-bit RGB/YUV444 or 8/10/10-bit YUV422 pixel data on a parallel
6output bus.
7
8Required properties:
9- compatible: "mediatek,<chip>-dpi"
10- reg: Physical base address and length of the controller's registers
11- interrupts: The interrupt signal from the function block.
12- clocks: device clocks
13 See Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
14- clock-names: must contain "pixel", "engine", and "pll"
15- port: Output port node with endpoint definitions as described in
16 Documentation/devicetree/bindings/graph.txt. This port should be connected
17 to the input port of an attached HDMI or LVDS encoder chip.

19Example:
20
21dpi0: dpi@1401d000 {
22 compatible = "mediatek,mt8173-dpi";
23 reg = <0 0x1401d000 0 0x1000>;
24 interrupts = <GIC_SPI 194 IRQ_TYPE_LEVEL_LOW>;
25 clocks = <&mmsys CLK_MM_DPI_PIXEL>,
26 <&mmsys CLK_MM_DPI_ENGINE>,
27 <&apmixedsys CLK_APMIXED_TVDPLL>;
28 clock-names = "pixel", "engine", "pll";
29
30 port {
31 dpi0_out: endpoint {
32 remote-endpoint = <&hdmi0_in>;
33 };
34 };
35};
