This is a bit confusing: this quirk does not work for Volteer
{
.callback = sof_rt5682_quirk_cb,
.matches = {
DMI_MATCH(DMI_PRODUCT_FAMILY, "Google_Volteer"),
DMI_MATCH(DMI_OEM_STRING, "AUDIO-MAX98373_ALC5682I_I2S_UP4"),
},
.driver_data = (void *)(SOF_RT5682_MCLK_EN |
SOF_RT5682_SSP_CODEC(0) |
SOF_SPEAKER_AMP_PRESENT |
SOF_MAX98373_SPEAKER_AMP_PRESENT |
SOF_RT5682_SSP_AMP(2) |
SOF_RT5682_NUM_HDMIDEV(4)),
},
Same for Brya and all usages of SSP_AMP(2)

and HEADPHONE_CODEC_PRESENT is not handled either.

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.
