+description: |
+ The mediatek MDP RDMA stands for Read Direct Memory Access.
+ It provides real time data to the back-end panel driver, such as DSI,
+ DPI and DP_INTF.
+ It contains one line buffer to store the sufficient pixel data.
+ RDMA device node 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.
