I think there is need to have some consolidation with current byt-rt5640 and byt-max98090. Since existing drivers and this set are using the same ACPI IDs "80860F28" for the ADSP and "10EC5640" codec ACPIID for the machine driver probing these drivers won't work together.
Liam's suggestion was to remove the current driver when all the bits are upstream
Yeah, I'm not against it but we must avoid regressions and perhaps try to do seamless handover if possible. It's always more nice to find regression in a small than big patch when bisecting :-)
One difference at the moment is that byt-rt5640 machines out there have differences in audio routings but those are not too difficult to handle in the same machine driver.
Bigger question how to handle platform part? I.e. can these use the same drivers and ADSP firmware? If they can, is the firmware available for distributions to take?
The two firmware are *not* compatible and that is the big reason why we can't reuse the parts available
Ok, so firmware appears to works on other than CR Baytrails too. Is it available in linux-firmware since if it's not when changing the platform drivers there will be obvious regressions to users?
I will send it this week, was focusing on getting the code done, whcih is now mostly complete.
