[PATCH 0/2] ASoC: Intel: sof_rt5682: quirk auto detection
A new feature to compose quirk value according to the result of amplifier and SoC type detection at runtime.
Brent Lu (2): ASoC: Intel: add helpers to detect SoCs ASoC: Intel: sof_rt5682: quirk auto detection

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.
Same for Brya and all usages of SSP_AMP(2)
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.

This is a bit confusing: this quirk does not work for Volteer

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.
Same for Brya and all usages of SSP_AMP(2)
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 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.

and HEADPHONE_CODEC_PRESENT is not handled either.
Headphone type will be detected later in the sof_audio_probe().

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'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.
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.
