MediaTek Read Direct Memory Access(RDMA) component used to do read DMA.
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.
