+* Mediatek Media Data Path 3
+
+Media Data Path 3 (MDP3) is used for scaling and color space conversion.
+
+Required properties (controller node):
+- compatible: "mediatek,mt8183-mdp3"
+- mediatek,scp: the node of system control processor (SCP), using the
+ remoteproc & rpmsg framework, see
+ Documentation/devicetree/bindings/remoteproc/mtk,scp.txt for details.
+- mediatek,mmsys: the node of mux(multiplexer) controller for HW connections.
+- mediatek,mm-mutex: the node of sof(start of frame) signal controller.
+- mediatek,mailbox-gce: the node of global command engine (GCE), used to
+ read/write registers with critical time limitation, see
+ Documentation/devicetree/bindings/mailbox/mtk-gce.txt for details.
+- mboxes: mailbox number used to communicate with GCE.
+- gce-subsys: sub-system id corresponding to the register address.
+- gce-event-names: in use event name list, used to correspond to event IDs.
+- gce-events: in use event IDs list, all IDs are defined in
+ 'dt-bindings/gce/mt8183-gce.h'.
+
+Required properties (all function blocks, child node):
+- compatible: Should be one of
+ "mediatek,mt8183-mdp-rdma" - read DMA
+ "mediatek,mt8183-mdp-rsz" - resizer
+ "mediatek,mt8183-mdp-wdma" - write DMA
+ "mediatek,mt8183-mdp-wrot" - write DMA with rotation
+ "mediatek,mt8183-mdp-ccorr" - color correction with 3X3 matrix
+- 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

+ component for path connectedness of HW
+ pipe control; Align with mdp_comp_of_ids[]
+ in mtk-mdp3-comp.c.
+- mdp-comp-ids(wdma & wrot only): Index of the output paths, the number aligns
+ with mdp_comp_matches[] in mtk-mdp3-comp.c.
+- iommus: should point to the respective IOMMU block with master port as
+ argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt 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.
+
+Required properties (input path selection node):
+- compatible:

+ "mediatek,mt8183-mdp-dl" - MDP direct link input path selection,
+ create a component for path connectedness
+ of HW pipe control; Align with
