1 Mediatek DPI Device
2 ===================
3
4 The Mediatek DPI function block is a sink of the display subsystem and
5 provides 8-bit RGB/YUV444 or 8/10/10-bit YUV422 pixel data on a parallel
6 output bus.
7
8 Required 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
20 Optional properties:
21 - pinctrl-names: Contain "default" and "sleep".
