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  the supported chips are mt2701, mt7623, mt8173 and mt8183.
11- reg: Physical base address and length of the controller's registers
12- interrupts: The interrupt signal from the function block.
13- clocks: device clocks
14  See Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
15- clock-names: must contain "pixel", "engine", and "pll"
16- port: Output port node with endpoint definitions as described in
17  Documentation/devicetree/bindings/graph.txt. This port should be connected
18  to the input port of an attached HDMI or LVDS encoder chip.
19
20Optional properties:
21- pinctrl-names: Contain "default" and "sleep".

23Example:
24
25dpi0: dpi@1401d000 {
26	compatible = "mediatek,mt8173-dpi";
27	reg = <0 0x1401d000 0 0x1000>;
28	interrupts = <GIC_SPI 194 IRQ_TYPE_LEVEL_LOW>;
29	clocks = <&mmsys CLK_MM_DPI_PIXEL>,
30		 <&mmsys CLK_MM_DPI_ENGINE>,
31		 <&apmixedsys CLK_APMIXED_TVDPLL>;
32	clock-names = "pixel", "engine", "pll";
33	pinctrl-names = "default", "sleep";
34	pinctrl-0 = <&dpi_pin_func>;
35	pinctrl-1 = <&dpi_pin_idle>;
36
37	port {
38		dpi0_out: endpoint {
39			remote-endpoint = <&hdmi0_in>;
40		};
41	};
42};
