Hello everyone,
This is a first version of a serie to add ADC support for Sun8i-A33. Based on asoc/for-next branch, last commit: 20d5c84bef067b7e804a163e2abca16c47125bad.
The first patch adds the support of ADC and microphones in the digital part (driver sun8i-codec). The second one adds the route between analog (sun8i-codec-analog) and digital (sun8i-codec) parts to have a functional ADC route on Sun8i-A33 device tree.
Tested on Allwinner R16 Parrot board with microphone 1 (external) and microphone 2 (headset).
I am not sure about the bias handling so if you have any comments on it, do not hesitate.
Thank you in advance!
Best regards,
