description: |
  Mediatek Read Direct Memory Access(RDMA) component used to read the
  data into DMA. 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.
