1Renesas R-Car sound
2
3Required properties:
4- compatible : "renesas,rcar_sound-<soctype>", fallbacks
5 "renesas,rcar_sound-gen1" if generation1, and
6 "renesas,rcar_sound-gen2" if generation2
7 "renesas,rcar_sound-gen3" if generation3
8 Examples with soctypes are:
9 - "renesas,rcar_sound-r8a7778" (R-Car M1A)
10 - "renesas,rcar_sound-r8a7790" (R-Car H2)
11 - "renesas,rcar_sound-r8a7791" (R-Car M2-W)
12 - "renesas,rcar_sound-r8a7795" (R-Car H3)
13- reg : Should contain the register physical address.
14 required register is
15 SRU/ADG/SSI if generation1
16 SRU/ADG/SSIU/SSI if generation2
17- rcar_sound,ssi : Should contain SSI feature.
18 The number of SSI subnode should be same as HW.
19 see below for detail.
20- rcar_sound,src : Should contain SRC feature.
21 The number of SRC subnode should be same as HW.
22 see below for detail.
23- rcar_sound,ctu : Should contain CTU feature.
24 The number of CTU subnode should be same as HW.
25 see below for detail.
26- rcar_sound,mix : Should contain MIX feature.
27 The number of MIX subnode should be same as HW.
28 see below for detail.
29- rcar_sound,dvc : Should contain DVC feature.
30 The number of DVC subnode should be same as HW.
31 see below for detail.
32- rcar_sound,dai : DAI contents.
33 The number of DAI subnode should be same as HW.
34 see below for detail.
35- #sound-dai-cells : it must be 0 if your system is using single DAI
36 it must be 1 if your system is using multi DAI
37- #clock-cells : it must be 0 if your system has audio_clkout
38 it must be 1 if your system has audio_clkout0/1/2/3
39- clock-frequency : for all audio_clkout0/1/2/3
40
41SSI subnode properties:
42- interrupts : Should contain SSI interrupt for PIO transfer
43- shared-pin : if shared clock pin
44- pio-transfer : use PIO transfer mode
45- no-busif : BUSIF is not ussed when [mem -> SSI] via DMA case
46- dma : Should contain Audio DMAC entry
47- dma-names : SSI case "rx" (=playback), "tx" (=capture)
48 SSIU case "rxu" (=playback), "txu" (=capture)
49
50SRC subnode properties:
51- dma : Should contain Audio DMAC entry
52- dma-names : "rx" (=playback), "tx" (=capture)
53
54DVC subnode properties:
55- dma : Should contain Audio DMAC entry
