  1. * R-Car Audio DMAC peri peri Device Tree bindings
  2. Required properties:
  3. - compatible: should be "renesas,rcar-audmapp"
  4. - #dma-cells: should be <1>, see "dmas" property below
  5. Example:
  6. audmapp: audio-dma-pp@0xec740000 {
  7. compatible = "renesas,rcar-audmapp";
  8. #dma-cells = <1>;
  9. reg = <0 0xec740000 0 0x200>;
  10. };
  11. * DMA client
  12. Required properties:
  13. - dmas: a list of <[DMA multiplexer phandle] [SRS << 8 | DRS]> pairs.
  14. where SRS/DRS are specified in the SoC manual.
  15. It will be written into PDMACHCR as high 16-bit parts.
  16. - dma-names: a list of DMA channel names, one per "dmas" entry
  17. Example:
  18. dmas = <&audmapp 0x2d00
  19. &audmapp 0x3700>;
  20. dma-names = "src0_ssiu0",
