This series has a few minor patches to address some SI issues. When a 4K 60Hz display is connected to Tahiti or Pitcairn there is a slight flickering near the bottom of the display. Disabling MCLK switching fixes that. (Other SI parts are likely affected too, but I didn't test them thoroughly enough to say.)
When enabling ASPM on Zen 4 with Tahiti and Oland, there are random hangs when the GPU usage is low. Disabling ASPM fixes that. At the moment I don't know if this is a platform-specific or GPU-specific issue and I don't think we can reasonably determine that without spending more time than we have. (Other SI parts may be affected, but I didn't test them for a long enough time to judge that.) Finally, there is a DC patch to change the minimum PLL dividers to the same value as the legacy non-DC display code. This doesn't fix any visible issue but I think it's still good to have just in case.
