      9description: |
     10  This describes the devicetree bindings for an external DMA engine to perform
     11  memory-to-memory or peripheral-to-memory data transfer capable of supporting
     12  16 channels, implemented in Socionext UniPhier SoCs.

     33      DMA request from clients consists of 2 cells:
     34        1. Channel index
     35        2. Transfer request factor number, If no transfer factor, use 0.
     36           The number is SoC-specific, and this should be specified with
     37           relation to the device to use the DMA controller.
