* Mediatek Media Data Path

Media Data Path is used for scaling and color space conversion.

Required properties (controller node):
- compatible: "mediatek,mt8173-mdp"
- mediatek,vpu: the node of video processor unit, see
  Documentation/devicetree/bindings/media/mediatek-vpu.txt for details.

Required properties (all function blocks, child node):
- compatible: Should be one of
        "mediatek,mt8173-mdp-rdma"  - read DMA
        "mediatek,mt8173-mdp-rsz"   - resizer
        "mediatek,mt8173-mdp-wdma"  - write DMA
        "mediatek,mt8173-mdp-wrot"  - write DMA with rotation
- reg: Physical base address and length of the function block register space
- clocks: device clocks, see
  Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
- power-domains: a phandle to the power domain, see
  Documentation/devicetree/bindings/power/power_domain.txt for details.

Required properties (DMA function blocks, child node):
- compatible: Should be one of
        "mediatek,mt8173-mdp-rdma"
        "mediatek,mt8173-mdp-wdma"
        "mediatek,mt8173-mdp-wrot"
- iommus: should point to the respective IOMMU block with master port as
  argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml
  for details.
- mediatek,larb: must contain the local arbiters in the current Socs, see
  Documentation/devicetree/bindings/memory-controllers/mediatek,smi-larb.txt
  for details.
