[PATCH v6 05/16] dt-bindings: media: mediatek: mdp3: add support MT8195 RDMA

[Moudy Ho]

Support for MT8195 RDMA has been added, allowing for
the configuration of multiple MDP3 pipes.
Furthermore, this particular device does not require
sharing SRAM with RSZ.

+description: |
+  MediaTek Read Direct Memory Access(RDMA) component used to do read DMA.
+  This type of component is configured when there are multiple MDP3 pipelines
+  that belong to different MMSYS subsystems.
+  It contains one line buffer to store the sufficient pixel data, and
+  must be siblings to the central MMSYS_CONFIG node.
+  For a description of the MMSYS_CONFIG binding, see
+  Documentation/devicetree/bindings/arm/mediatek/mediatek,mmsys.yaml
+  for details.
