* 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 << 8 | DRS]> pairs.
where SRS/DRS are specified in the SoC manual.
It will be written into PDMACHCR as high 16-bit parts.
- dma-names: a list of DMA channel names, one per "dmas" entry
Example:
dmas = <&audmapp 0x2d00
&audmapp 0x3700>;
dma-names = "src0_ssiu0",
"dvc0_ssiu0";
