This mainly affects pcie-qcom.c, so it looks like Stanimir should have
been copied on this, but wasn't. Please include him on the next
iteration.
This will also need to be updated to apply on v5.19-rc1:
03:21:47 ~/linux (next)$ git checkout -b wip/baruch-ipq6018-v6 v5.19-rc1
Switched to a new branch 'wip/baruch-ipq6018-v6'
03:21:55 ~/linux (wip/baruch-ipq6018-v6)$ git am m/v6_20220207_baruch_pci_ipq6018_platform_support.mbx
Applying: PCI: dwc: tegra: move GEN3_RELATED DBI register to common header
Applying: PCI: qcom: Define slot capabilities using PCI_EXP_SLTCAP_*
Applying: PCI: qcom: Add IPQ60xx support
error: patch failed: drivers/pci/controller/dwc/pcie-qcom.c:1531
error: drivers/pci/controller/dwc/pcie-qcom.c: patch does not apply
Patch failed at 0003 PCI: qcom: Add IPQ60xx support
