At ChromeOS we work with Nuvoton hw engineers on driver for this nice
chip as well.
Here is current driver code
https://github.com/anatol/linux/blob/nau8825/sound/soc/codecs/nau8825.c
The functionality is mostly ready. Our driver handles playback,
capture, mic jack detection, an button presses (4 buttons according
Android specification). We need to resolve a few remaining issues,
such as
- chip needs better way to recognize high-impedance input (e.g. Bose
Quiet Comfort 15 headset)
- implement headset cross talk automatic configuration
- general code cleanup
But otherwise driver is functional and used for testing in our next
generation device.
What do you think about joining efforts on this software development
to make great driver for this chip?
