   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 - 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.
  18
  19 Optional properties:
  20 - pinctrl-names: Contain "default" and "sleep".
