Hi Sergio, thanks for your continuing work on mt7621-pci. I've looked through you patches and while things seem to make sense I don't have the expertise to review them properly. I've just a build a kernel based on v5.6.3 with the patches listed below applied from your various emails over the last couple of months. I have confirm that PCI works and in particular I don't get the cold-boot hangs that are common without these patches. So that is an excellent result.
