|
|
Required properties for the following compatibles:
|
- "allwinner,sun6i-a31-codec"
|
- "allwinner,sun8i-a23-codec"
|
- "allwinner,sun8i-h3-codec"

|
source. Valid names include:
|
|
Audio pins on the SoC:
|

|
"HPCOM"
|
"LINEIN" (not on sun8i-v3s)
|
"LINEOUT" (not on sun8i-a23 or sun8i-v3s)
|
"MIC1"
|
"MIC2" (not on sun8i-v3s)
|
"MIC3" (sun6i-a31 only)
|
|
Microphone biases from the SoC:
|
"HBIAS"
|
"MBIAS" (not on sun8i-v3s)
|
|
Board connectors:
|
"Headphone"
|
"Headset Mic"
|
"Line In"
|
"Line Out"
|
"Mic"
|
"Speaker"
|
|
Required properties for the following compatibles:
|
- "allwinner,sun8i-a23-codec"

|
- "allwinner,sun8i-v3s-codec"
|
- allwinner,codec-analog-controls: A phandle to the codec analog controls
|
block in the PRCM.
