Bug description:
The patchset will be merged to upstream kernel v6.1, the unstable
kernel will have the patchset automatically after the v6.1 is ready.
The oem-5.17 kernel doesn't support this AMD generation platform yet,
so this patchset is useless for oem-5.17 so far.
[Impact]
On the AMD PS platforms, the internal mic can't be detected
and there is no internal mic for users to use.
[Fix]
Backport 13 patches from linux-next kernel to fix this problem.
[Test]
boot the patched kernel on the machine, after loging into the
desktop, open the gnome-sound-setting, there is
internal mic, and could record sound via internal mic.
[Where problems could occur]
This only impacts intenal mic support on AMD ps machines, it will
match the pci device revision and apply the driver according to
match result, in theory it will not bring regression on non-amd-ps
machines.
