1* R-Car Audio DMAC peri peri Device Tree bindings
2
3Required properties:
4- compatible: should be "renesas,rcar-audmapp"
5- #dma-cells: should be <1>, see "dmas" property below
6
7Example:
8 audmapp: audio-dma-pp@0xec740000 {
9 compatible = "renesas,rcar-audmapp";
10 #dma-cells = <1>;
11
12 reg = <0 0xec740000 0 0x200>;
13 };

16* DMA client
17
18Required properties:
19- dmas: a list of <[DMA multiplexer phandle] [SRS << 8 | DRS]> pairs.
20 where SRS/DRS are specified in the SoC manual.
21 It will be written into PDMACHCR as high 16-bit parts.
22- dma-names: a list of DMA channel names, one per "dmas" entry
23
24Example:
25
26 dmas = <&audmapp 0x2d00
27 &audmapp 0x3700>;
28 dma-names = "src0_ssiu0",
29 "dvc0_ssiu0";
