** Description changed: - This bug is for tracking purpose. + [Impact] + We have backported the amd renoir audio driver to oem-5.6 and focal + kernel, recently we found if the dmic is working and we suspend and + resume, the dmic can't record the sound after resume. + + [Fix] + After resuming, the driver needs to restore 2 more registers, then the + dmic could record the sound. + + [Test Case] + Boot the kernel with this patch, open the sound-setting and run suspend + and resume, then use arecord to record the sound, verify the sound is + successfully recorded by aplaying it. + + [Regression Risk] + Low, this patch is verified on the amd renoir machine, and this patch + got ack from AMD engineer.
