1 Mediatek DSI Device
2 ===================
3
4 The Mediatek DSI function block is a sink of the display subsystem and can
5 drive up to 4-lane MIPI DSI output. Two DSIs can be synchronized for dual-
6 channel output.
7
8 Required properties:
9 - compatible: "mediatek,<chip>-dsi"
10 - the supported chips are mt2701, mt7623, mt8167, 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 "engine", "digital", and "hs"
16 - phys: phandle link to the MIPI D-PHY controller.
17 - phy-names: must contain "dphy"
18 - port: Output port node with endpoint definitions as described in
19 Documentation/devicetree/bindings/graph.txt. This port should be connected
20 to the input port of an attached DSI panel or DSI-to-eDP encoder chip.
21
22 Optional properties:
23 - resets: list of phandle + reset specifier pair, as described in [1].
