description: |
  DPU (Display Processor Unit) is the Display Controller for the Unisoc SoCs
  which transfers the image data from a video memory buffer to an internal
  LCD interface.

properties:
  compatible:
    const: sprd,sharkl3-dpu

  reg:

  interrupts:
    maxItems: 1

  clocks:
    minItems: 2

  clock-names:
    items:
      - const: clk_src_128m
      - const: clk_src_384m

  port:
    type: object
    description:
      A port node with endpoint definitions as defined in
      Documentation/devicetree/bindings/media/video-interfaces.txt.
      That port should be the output endpoint, usually output to
      the associated DSI.
