1 Renesas R-Car sound
3 Required properties:
4 - compatible : "renesas,rcar_sound-<soctype>", fallbacks
5 "renesas,rcar_sound-gen1" if generation1, and
6 "renesas,rcar_sound-gen2" if generation2
7 Examples with soctypes are:
8 - "renesas,rcar_sound-r8a7790" (R-Car H2)
9 - "renesas,rcar_sound-r8a7791" (R-Car M2-W)
10 - reg : Should contain the register physical address.
11 required register is
12 SRU/ADG/SSI if generation1
13 SRU/ADG/SSIU/SSI if generation2
14 - rcar_sound,ssi : Should contain SSI feature.
15 The number of SSI subnode should be same as HW.
16 see below for detail.
17 - rcar_sound,src : Should contain SRC feature.
18 The number of SRC subnode should be same as HW.
19 see below for detail.
20 - rcar_sound,dvc : Should contain DVC feature.
21 The number of DVC subnode should be same as HW.
22 see below for detail.
23 - rcar_sound,dai : DAI contents.
24 The number of DAI subnode should be same as HW.
25 see below for detail.
27 SSI subnode properties:
28 - interrupts : Should contain SSI interrupt for PIO transfer
29 - shared-pin : if shared clock pin
30 - pio-transfer : use PIO transfer mode
31 - no-busif : BUSIF is not ussed when [mem -> SSI] via DMA case
32 - dma : Should contain Audio DMAC entry
33 - dma-names : SSI case "rx" (=playback), "tx" (=capture)
34 SSIU case "rxu" (=playback), "txu" (=capture)
36 SRC subnode properties:
37 - dma : Should contain Audio DMAC entry
38 - dma-names : "rx" (=playback), "tx" (=capture)
40 DVC subnode properties:
41 - dma : Should contain Audio DMAC entry
42 - dma-names : "tx" (=playback/capture)
44 DAI subnode properties:
45 - playback : list of playback modules
46 - capture : list of capture modules
