Renesas R-Car sound
Required properties:
- compatible : "renesas,rcar_sound-<soctype>", fallbacks
"renesas,rcar_sound-gen1" if generation1, and
"renesas,rcar_sound-gen2" if generation2
"renesas,rcar_sound-gen3" if generation3
Examples with soctypes are:
- "renesas,rcar_sound-r8a7778" (R-Car M1A)
- "renesas,rcar_sound-r8a7790" (R-Car H2)
- "renesas,rcar_sound-r8a7791" (R-Car M2-W)
- "renesas,rcar_sound-r8a7795" (R-Car H3)
- reg : Should contain the register physical address.
required register is
SRU/ADG/SSI if generation1
SRU/ADG/SSIU/SSI if generation2
- rcar_sound,ssi : Should contain SSI feature.
The number of SSI subnode should be same as HW.
see below for detail.
- rcar_sound,src : Should contain SRC feature.
The number of SRC subnode should be same as HW.
see below for detail.
- rcar_sound,ctu : Should contain CTU feature.
The number of CTU subnode should be same as HW.
see below for detail.
- rcar_sound,mix : Should contain MIX feature.
The number of MIX subnode should be same as HW.
see below for detail.
- rcar_sound,dvc : Should contain DVC feature.
The number of DVC subnode should be same as HW.
see below for detail.
- rcar_sound,dai : DAI contents.
The number of DAI subnode should be same as HW.
see below for detail.
- #sound-dai-cells : it must be 0 if your system is using single DAI
it must be 1 if your system is using multi DAI
- #clock-cells : it must be 0 if your system has audio_clkout
it must be 1 if your system has audio_clkout0/1/2/3
- clock-frequency : for all audio_clkout0/1/2/3
SSI subnode properties:
- interrupts : Should contain SSI interrupt for PIO transfer
- shared-pin : if shared clock pin
- pio-transfer : use PIO transfer mode
- no-busif : BUSIF is not ussed when [mem -> SSI] via DMA case
- dma : Should contain Audio DMAC entry
- dma-names : SSI case "rx" (=playback), "tx" (=capture)
SSIU case "rxu" (=playback), "txu" (=capture)
SRC subnode properties:
- dma : Should contain Audio DMAC entry
- dma-names : "rx" (=playback), "tx" (=capture)
DVC subnode properties:
- dma : Should contain Audio DMAC entry
- dma-names : "tx" (=playback/capture)
DAI subnode properties:
- playback : list of playback modules
- capture : list of capture modules
