Hi Chen-Yu,

Thank you for the review.

Update the driver to use SND_SOC_DAPM_AIF_IN instead of
SND_SOC_DAPM_DAC.

Set the route names so it must be updated on the device tree too.

This patch looks OK, but having the DTS changes in the same patch
probably isn't a good idea. I would really like to see this series
merged for 4.11, so we can expose a good mixer interface to userspace
during the first kernel release supporting the A33 codec. That likely
means some breakage between when the asoc bits and the dts bits land
though.

Yes, as it means some breakage, I did not know if 2 patches will be fine 
or not.


Maxime, any ideas?


I asked him directly and he agrees.

It is fine for me so I will send a v2 with this patch split.

Best regards,
