Considering certain dependency patches have been merged to
pci/endpoint and other dependency patches have been merged to
pci/controller/dwc, perhaps it is best if you split this series:

Series 1 based on pci/endpoint: with patch 1/5 and 2/5.
Series 2 based on pci/controller/dwc: with patch 5/5.

Just a friendly suggestion to make Bjorn's life easier
(and grease the path of your patch) ;) [0]


Kind regards,
Niklas
