1* Qualcomm Technologies Inc. SDM845 ASoC sound card driver
2
3This binding describes the SDM845 sound card, which uses qdsp for audio.
4
5- compatible:
6	Usage: required
7	Value type: <stringlist>
8	Definition: must be one of this
9			"qcom,sdm845-sndcard"
10			"qcom,db845c-sndcard"
11			"lenovo,yoga-c630-sndcard"
12
13- audio-routing:
14	Usage: Optional
15	Value type: <stringlist>
16	Definition:  A list of the connections between audio components.
17		  Each entry is a pair of strings, the first being the
18		  connection's sink, the second being the connection's
19		  source. Valid names could be power supplies, MicBias
20		  of codec and the jacks on the board.
21
22- model:
23	Usage: required
24	Value type: <stringlist>
25	Definition: The user-visible name of this sound card.
26
27- aux-devs
28	Usage: optional
29	Value type: <array of phandles>
30	Definition: A list of phandles for auxiliary devices (e.g. analog
31		    amplifiers) that do not appear directly within the DAI
32		    links. Should be connected to another audio component
33		    using "audio-routing".
34
35= dailinks
36Each subnode of sndcard represents either a dailink, and subnodes of each
37dailinks would be cpu/codec/platform dais.
38
39- link-name:
40	Usage: required
41	Value type: <string>
42	Definition: User friendly name for dai link
43
44= CPU, PLATFORM, CODEC dais subnodes
45- cpu:
46	Usage: required
47	Value type: <subnode>
48	Definition: cpu dai sub-node
49
50- codec:
51	Usage: required
52	Value type: <subnode>
53	Definition: codec dai sub-node
54
55- platform:
56	Usage: Optional
57	Value type: <subnode>
58	Definition: platform dai sub-node
59
60- sound-dai:
61	Usage: required
62	Value type: <phandle>
63	Definition: dai phandle/s and port of CPU/CODEC/PLATFORM node.
