For consistency to what's in linux-sunxi.git, I will remove the "-In" from 
the Mic names in v7.

For FM, do we? I don't know. Are there ALSA devices which output to FM?

Aha, Mic1 is there in <https://github.com/linux-sunxi/linux-sunxi.git> 
branch "sunxi-next".
In <git://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux.git> 
branch "sunxi/for-next", it's not there. 
This patch is for the latter.

I'm currently rebasing on the former, but it will take some time. 
The differences between these driver versions are:
- Mic1 Preamplifier is registered as PGA instead of switch in the former.
- Mic1 is already an input in the former.
- VMIC is handled in the former.
- ADC Capturing support exists in the former.
That's it.

I'll retest a patch based on the former...

Yeah, I think I found a nicer way to do it in v6.

Thanks,
