** Description changed:
- this bug is for tracking purpose.
+ This patchset is for mainline kernel-5.8, after backporting to 5.6,
+ there is no need to change anything, but after backporting to 5.4
+ kernel, because of API differences, need to do some change to adapt
+ to 5.4 kernel's API. So there is one more patch for focal than for
+ oem-5.6.
+
+ [Impact]
+ We have a couple of LENOVO machines which has amd renoir audio on
+ them, our kernel doesn't have the driver for it yet.
+
+ [Fix]
+ amd just upstreamed the driver, it is for kernel-5.8, we backport
+ them to ubunt kernel.
+
+ [Test Case]
+ boot the kernel with those patches, we could see a sound card named
+ "acp" and the dmic on it could record sound via arecord.
+
+ [Regression Risk]
+ Low, just adding a new driver, no change to existing drivers.
