Re: [PATCH] ASoC: Intel: sof_rt5682: Add max98390 echo reference support

The commit subject is not really correct, it's not about echo reference support, it's really about basic support for max98390

My main objection is that there's a rather large copy-paste from the max98373 code, when the only change I can see is the device and dai names, see below

I don't get why this is different from the 'Google Brya' quirk above - which is missing the BT_OFFLOAD information.

If this is not for the same device/configuration, we should have different patches or a better set of comments that keeps track of the differences.

And now that I think of it, this may be a mistake. Usually the headset uses SSP0, the amp SSP1 and BT offload SSP2. I am pretty sure you cannot use SSP2 for BT offload as well as the amplifier links, the configurations are different.
