Subject: Re: [PATCH] ASoC: Intel: sof_rt5682: Add max98390 echo reference support
Date: Tue, 3 Aug 2021 08:46:49 -0500	[thread overview]
Message-ID: <1160d111-fe9c-3a66-fab0-e11675b86169@linux.intel.com> (raw)
In-Reply-To: <20210803092013.10749-1-mark_hsieh@wistron.corp-partner.google.com>

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

you've even left two references to 98373 in this structure...

... and until this line, I don't see much difference with 98373

again it really seems like this is the only difference?

this should be in a separate patch?

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.
