TLV320AIC3110: Assistance Needed with Device-Tree Configuration for TLV320AIC3110

Dharmendra Savaliya

Part Number: TLV320AIC3110

Tool/software:

We are currently testing the following configuration in the device-tree [linux-6.6.36] to verify the TLV320AIC3110 codec with TPA3110D2PWP amplifier.

However, we are not able to get voltage at MICBIAS & not getting audio at headset playback.

Request:
Please provide support with the correct device-tree configuration for TLV320AIC3110.

Schematic of hardware design is available in support ticket below. We have also attached device tree for review.
