[alsa-devel] [PATCH 1/2] dt-bindings: sound: Add TLV320ADCx140 dt bindings
Add dt bindings for the TLV320ADCx140 Burr-Brown ADC. The initial support is for the following:
TLV320ADC3140 - http://www.ti.com/lit/gpn/tlv320adc3140 TLV320ADC5140 - http://www.ti.com/lit/gpn/tlv320adc5140 TLV320ADC6140 - http://www.ti.com/lit/gpn/tlv320adc6140

Add the tlv320adcx140 codec driver family.
The TLV320ADCx140 is a Burr-Brown™ highperformance, audio analog-to-digital converter (ADC) that supports simultaneous sampling of up to four analog channels or eight digital channels for the pulse density modulation (PDM) microphone input. The device supports line and microphone inputs, and allows for both single-ended and differential input configurations.

_DSP_A and _DSP_B are two different format so I'd expect the device to be configured differently for them, or for only one to be supported.

You could also just offer this control to userspace, it's not *essential* to have this operation though it can help with glitching during stream startup.

Does this actually need a specific property or could you support the regulator API and then use regulator_get_optional() to figure out if an external AVDD is attached?

Thanks for the review

Ack. I will need to adjust the TX offset for these. I will do add a prepare call back and set the offset there. These can fall through since TDM is default.

This is unmuted through volume control. I can remove this as the device is muted when the volume register is set to 0. That will force the user to have to set a volume.

Yes we could set internal AREG bit if no supply is given.

No that is an artifact of my development I can move everything to codec_probe
