|
|
|
|
Required properties:
|
|
- compatible : "renesas,rcar_sound-<soctype>", fallbacks
|
|
"renesas,rcar_sound-gen1" if generation1, and
|
|
"renesas,rcar_sound-gen2" if generation2
|
|

|
|
Examples with soctypes are:
|
|

|
|
- dma : Should contain Audio DMAC entry
|
|
- dma-names : SSI case "rx" (=playback), "tx" (=capture)
