|
|
|
|
Required properties:
|
|
- compatible : "renesas,rcar_sound-gen1" if generation1
|
|
"renesas,rcar_sound-gen2" if generation2
|
|
- 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,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.
|
|
|
|
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
|
|
|
|
SRC subnode properties:
|
|
no properties at this point
|
|
|
|
DAI subnode properties:
|
|
- playback : list of playback modules
|
|
- capture : list of capture modules
|
|
|
|
