PCI: rockchip-dwc: add PCIe bifurcation PCI: rockchip: add a lane-map to rockchip pcie driver I think we decided [1] to use "rockchip-dwc" for this driver to distinguish it from the pcie-rockchip-host.c driver. So both of these should use "PCI: rockchip-dwc:" as the prefix. At least for the drivers/pci/ patches, capitalize the first word of the subject, i.e., "Add PCIe bifurcation" and "Add lane-map ..." I don't know the dt-bindings convention (I would use "git log --oneline" to find out). s/pcie/PCIe/ in subjects, commit logs, comments, etc. Wrap commit logs to fill 75 columns and add blank lines between paragraphs. Readers should not need to wonder "oh, the previous line was shorter than usual; is this one a new paragraph?"
