Hi, Existing da7210 driver is very minimalistic in terms of functionality. It supports only one output i.e. head phone. da7210 codec hardware supports many more IOs and features.
Here is a patch series that is "feature update" in nature. This adds support for all inputs(MIC L-R, AUX1 L-R, AUX2) and outputs (OUT1 L-R, OUT2) as well as following features,
- ADC and DAC equalizers - Mute - Zero cross - Other DAI word lengths, format and mode - ALC - Noise suppression - High pass and voice filters - DAPM
This series also contains a small bug fix for head phone volume control.
Thanks,
