1* Mediatek Media Data Path
2
3Media Data Path is used for scaling and color space conversion.
4
5Required properties (controller node):
6- compatible: "mediatek,mt8173-mdp"
7- mediatek,vpu: the node of video processor unit, see
8  Documentation/devicetree/bindings/media/mediatek-vpu.txt for details.
9
10Required properties (all function blocks, child node):
11- compatible: Should be one of
12        "mediatek,mt8173-mdp-rdma"  - read DMA
13        "mediatek,mt8173-mdp-rsz"   - resizer
14        "mediatek,mt8173-mdp-wdma"  - write DMA
15        "mediatek,mt8173-mdp-wrot"  - write DMA with rotation
16- reg: Physical base address and length of the function block register space
17- clocks: device clocks, see
18  Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
19- power-domains: a phandle to the power domain, see
20  Documentation/devicetree/bindings/power/power_domain.txt for details.
21
22Required properties (DMA function blocks, child node):
23- compatible: Should be one of
24        "mediatek,mt8173-mdp-rdma"
25        "mediatek,mt8173-mdp-wdma"
26        "mediatek,mt8173-mdp-wrot"
27- iommus: should point to the respective IOMMU block with master port as
28  argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt
29  for details.
30- mediatek,larb: must contain the local arbiters in the current Socs, see
31  Documentation/devicetree/bindings/memory-controllers/mediatek,smi-larb.txt
32  for details.
