I asked google but they prefer not removing this string so it seems to > me that one extra DMI quirk is needed. I find this pretty funny. The PRODUCT_FAMILY was added to reduce the number of quirks, but of course there's a variant that has nothing to do with this 'FAMILY'. You should add a comment on this, to make sure this information remains in the code and we don't lose it during code cleanups. > > { > .callback = sof_rt5682_quirk_cb, > .matches = { > DMI_MATCH(DMI_PRODUCT_FAMILY, "Google_Hatch"), > }, > .driver_data = (void *)(SOF_RT5682_MCLK_EN | > SOF_RT5682_MCLK_24MHZ | > SOF_RT5682_SSP_CODEC(0) | > SOF_SPEAKER_AMP_PRESENT | > SOF_RT5682_SSP_AMP(1)), > }, > > The other way is using acpi_dev_present() in probe to update the quirk with correct > codec setting. Which one do you think is better? The DMI quirk you added is probably better for now, I don't know if the odds of getting things right with acpi_dev_present() are that high or if we are going to get even more variants on top of this variant (e.g. tweeter/booster cases...). If we get too many quirks we'll see later if we can simplify. So if you don't mind adding a comment on the 'Dooly' quirk in a v3 that series is good to go. Thank you!
