Mediatek DSI Device
===================

The Mediatek DSI function block is a sink of the display subsystem and can
drive up to 4-lane MIPI DSI output. Two DSIs can be synchronized for dual-
channel output.

Required properties:
- compatible: "mediatek,<chip>-dsi"
- the supported chips are mt2701, mt7623, mt8167, mt8173 and mt8183.
- reg: Physical base address and length of the controller's registers
- interrupts: The interrupt signal from the function block.
- clocks: device clocks
  See Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
- clock-names: must contain "engine", "digital", and "hs"
- phys: phandle link to the MIPI D-PHY controller.
- phy-names: must contain "dphy"
- port: Output port node with endpoint definitions as described in
  Documentation/devicetree/bindings/graph.txt. This port should be connected
  to the input port of an attached DSI panel or DSI-to-eDP encoder chip.

Optional properties:
- resets: list of phandle + reset specifier pair, as described in [1].
