To get rid of increasing board_ids array with similar quirks for every
new platform, we implement a special board config 'sof_rt5682_auto' to
compose quirk value at runtime. It detects SoC and amplifier type to
determine the quirk value.

Overall I doubt that the SOC alone can tell you what the quirk is.
Maybe it's a default to avoid repeats of the same baseline
configuration, but there's not much else that can be infer from an SOC
definition in light of the creativity of our hardware friends who
routinely swap interfaces.

I checked Volteer reference kit, it should use SSP1 for amplifier. It seems to me
this quirk is for some customer variants which implements MAX98373 on SSP2.

It's a compromise that Google implements amplifiers on SSP2 on Brya so they can
connect SDW codec to SSP1 pins, but we asked customers to implement amplifiers
on SSP1 to reserve BT offload capability.

I'm thinking about using kernel module parameters for those boards which do not
use default SSP port allocation. Not sure it's doable for machine driver module.

I appreciate what you are trying to suggest, and I am all for trying to
put this proliferation of quirks under control, but the autodetection
based on rules seems out-of-reach if we don't first cleanup the existing
quirks.
If "volteer" and "brya" mean different things to different people, and
reference and derivatives are not well identified, the odds of
regressions seem very high to me.

That's not a working solution IMHO, the kernel parameters should be used
by expert developers only for specific and short-term debug. It's not
possible to add a dependency on kernel parameters, that would prevent a
kernel update.

The reason that we need so many DMI quirks is that we are not able to know
which SSP port is used by headphone and amplifier. However, it seems to me
that platform and machine driver does not care about the DAI name.
I've tested to rename the backend DAIs as something like 'SSP-HP', 'SSP-SPK',
and 'SSP-BT' so we don't need to create new board info just because the SSP
port is different. However, we need to modify topology since DAI name is
changed.

Right, and it really doesn't work for distributions.
