* Qualcomm Technologies APQ8016 SBC ASoC machine driver
|
|
This node models the Qualcomm Technologies APQ8016 SBC ASoC machine driver
|
|
Required properties:
|
|
- compatible : "qcom,apq8016-sbc-sndcard"
|
|
- pinctrl-N : One property must exist for each entry in
|
pinctrl-names. See ../pinctrl/pinctrl-bindings.txt
|
for details of the property values.
|
- pinctrl-names : Must contain a "default" entry.
|
- reg : Must contain an address for each entry in reg-names.
|
- reg-names : A list which must include the following entries:
|
* "mic-iomux"
|
* "spkr-iomux"
|
- qcom,model : Name of the sound card.
|
|
- qcom,audio-routing : A list of the connections between audio components.
|
Each entry is a pair of strings, the first being the
|
connection's sink, the second being the connection's
|
source. Valid names could be power supplies, MicBias
|
of msm8x16_wcd codec and the jacks on the board:
|
|
Power supplies:
|
* MIC BIAS External1
|
* MIC BIAS External2
|
* MIC BIAS Internal1
|
* MIC BIAS Internal2
|
|
Board connectors:
|
* Headset Mic
|
* Secondary Mic
|
* DMIC
|
* Ext Spk
|
|
Optional properties:
|
|
- aux-devs : A list of phandles for auxiliary devices (e.g. analog
|
amplifiers) that do not appear directly within the DAI
|
links. Should be connected to another audio component
|
using "qcom,audio-routing".
|
|
Dai-link subnode properties and subnodes:
|
|
Required dai-link subnodes:
|
|
- cpu : CPU sub-node
|
- codec : CODEC sub-node
|
|
Required CPU/CODEC subnodes properties:
|
|
-link-name : Name of the dai link.
|
-sound-dai : phandle/s and port of CPU/CODEC
|
