I think @Frank's series will go via the DMA engine tree, I will do my best to review your DWC changes: [PATCH v2 00/13] PCI: dwc: Various fixes and cleanups Link: https://lore.kernel.org/linux-pci/20220503212300.30105-1-Sergey.Semin@xxxxxxxxxxxxxxxxxxxx/ but I can't guarantee they will make v5.19 and after that I will be AFK for two months, which is not good either, I will coordinate with Bjorn to see what can we do on this, I am sorry but that's all I have to offer at this stage.
