| * R-Car Audio DMAC peri peri Device Tree bindings |
| |
| Required properties: |
| - compatible: should be "renesas,rcar-audmapp" |
| - #dma-cells: should be <1>, see "dmas" property below |
| |
| Example: |
| audmapp: audio-dma-pp@0xec740000 { |
| compatible = "renesas,rcar-audmapp"; |
| #dma-cells = <1>; |
| |
| reg = <0 0xec740000 0 0x200>; |
| }; |

| * DMA client |
| |
| Required properties: |
| - dmas: a list of <[DMA multiplexer phandle] [SRS/DRS value]> pairs, |
| where SRS/DRS values are fixed handles, specified in the SoC |
| manual as the value that would be written into the PDMACHCR. |
| - dma-names: a list of DMA channel names, one per "dmas" entry |
| |
| Example: |
| |
| dmas = <&audmapp 0x2d00 |
| &audmapp 0x3700>; |
| dma-names = "src0_ssiu0", |
| "dvc0_ssiu0"; |
