Subject: [PATCH] ASoC: SOF: Intel: Baytrail: clarify mutual exclusion with Atom/SST driver
Git-commit: df7257e544faf838c3e7ad6b4e89ffe59e87f5e1
Patch-mainline: v5.5-rc1
References: jsc#SLE-16518
Some distros select all options blindly, which leads to confusion and
bug reports. Since SOF does not support Baytrail-CR for now, and
UCM/topology files are still being propagated to downstream distros,
make SOF on Baytrail an opt-in option that first require distros to
opt-out of existing defaults.

This adds support for Sound Open Firmware for Intel(R) platforms
