BTW, there are some dmic dynamically detection patches, we integrate them too. [Fix] Backport 1 patch from upstream. [Test Case] boot the kernel with the patch on amd renoir machines (lenovo machines), the audio driver works well (via command line like aplay or areord), then upgrade the alsa-lib and alsa-ucm-conf to 1.2.3.2, now we could see the audio devices from gnome, and they work well. [Regression Risk] Low, this SRU are only specific to soc/amd/renoir, and we already tested on 2 lenovo machines, their audio worked as before.
