Unfortunately commit f8c55dc6e828324fc58c0bb32d72a5a4041d1c3b
broke DMA on the mt7621, so I cannot test anything since then.

I apply these patches onto
  4cafd03a916e2f7c15520fed0b7894cf25f4ecc5
and get

[    0.570000] mt7621-pci 1e140000.pcie: missing "reg" property
[    0.580000] mt7621-pci 1e140000.pcie: Parsing DT failed
[    0.590000] mt7621-pci: probe of 1e140000.pcie failed with error -22

and no working PCI.

Thanks,
NeilBrown
