ASoC: dt-bindings: convert tlv320aic31xx.txt to yaml
Browse files Browse the repository at this point in the history
Convert binding doc tlv320aic31xx.txt to yaml format.
Additional change:
- add i2c node in example.
- replace MICBIAS_OFF with MICBIAS_2_0v in example because MICBIAS_OFF have
been defined in header file.
- add ref to dai-common.yaml.
- add #sound-dai-cells.

Fix below warning:
arch/arm64/boot/dts/freescale/imx8mq-zii-ultra-rmb3.dtb: /soc@0/bus@30800000/i2c@30a30000/codec@18:
	failed to match any schema with compatible: ['ti,tlv320dac3100']

CODEC output pins:
* HPL
* HPR
* SPL, devices with stereo speaker amp
* SPR, devices with stereo speaker amp
* SPK, devices with mono speaker amp
* MICBIAS
CODEC input pins:
* MIC1LP, devices with ADC
* MIC1RP, devices with ADC
* MIC1LM, devices with ADC
* AIN1, devices without ADC
* AIN2, devices without ADC
The pins can be used in referring sound node's audio-routing property.
