IPQ8074 has two PCIe ports both are based on synopsis designware PCIe controller. while it was assumed that PCIe support for IPQ8074 was already available. PCIe was not functional until now. This patch series adds support for PCIe ports on IPQ8074. First PCIe port is of gen2 synposis version is 2_3_2 which has already been enabled. But it had some problems on phy init and needed dt updates. Second PCIe port is gen3 synopsis version is 2_9_0. This series adds support for this PCIe port while fixing dt nodes. Patch 1 on this series depends on qcom pcie bindings patch https://lkml.org/lkml/2020/6/24/162 Sivaprakash Murugesan (9): dt-bindings: pci: Add ipq8074 gen3 pci compatible dt-bindings: phy: qcom,qmp: Add dt-binding for ipq8074 gen3 pcie phy clk: qcom: ipq8074: Add missing bindings for pcie clk: qcom: ipq8074: Add missing clocks for pcie phy: qcom-qmp: use correct values for ipq8074 gen2 pcie phy init phy: qcom-qmp: Add compatible for ipq8074 pcie gen3 qmp phy pci: dwc: qcom: do phy power on before pcie init pci: qcom: Add support for ipq8074 pci controller arm64: dts: ipq8074: Fixup pcie dts nodes
No comment on the patches themselves, but please update the subject lines so they follow the conventions: dt-bindings: PCI: qcom: Add ipq8074 PCIe Gen3 support dt-bindings: phy: qcom,qmp: Add ipq8074 PCIe Gen3 phy clk: qcom: ipq8074: Add missing bindings for PCIe clk: qcom: ipq8074: Add missing clocks for PCIe phy: qcom-qmp: Use correct values for ipq8074 PCIe Gen2 PHY init PCI: qcom: Do PHY power on before PCIe init PCI: qcom: Add ipq8074 PCIe controller support arm64: dts: ipq8074: Fixup PCIe DTS nodes Also fix the same things in the commit logs, e.g., consistently use "PCIe" instead of "pcie", "Gen2" instead of "gen2", etc. For example: ipq8074 has two PCIe ports while the support for gen2 pcie port ... What's the point of using "PCIe" for the first and "pcie" for the second? You can learn all this by using "git log" and "git log --online".
