Patch series adds support for enabling the PCIe controller and UNIPHY found on Qualcomm IPQ5332 platform. PCIe0 is Gen3 X1 and PCIe1 is Gen3 X2 are added. This series combines [1] and [2]. [1] introduces IPQ5018 PCIe support and [2] depends on [1] to introduce IPQ5332 PCIe support. Since the community was interested in [2] (please see [3]), tried to revive IPQ5332's PCIe support with v2 of this patch series. v2 of this series pulled in the phy driver from [1] tried to address comments/feedback given in both [1] and [2]. 1. Enable IPQ5018 PCI support (Nitheesh Sekar) - https://lore.kernel.org/all/20231003120846.28626-1-quic_nsekar@xxxxxxxxxxx/ 2. Add PCIe support for Qualcomm IPQ5332 (Praveenkumar I) - https://lore.kernel.org/linux-arm-msm/20231214062847.2215542-1-quic_ipkumar@xxxxxxxxxxx/ 3. Community interest - https://lore.kernel.org/linux-arm-msm/20240310132915.GE3390@thinkpad/ v3: * Update the cover letter with the sources of the patches * Rename the dt-bindings yaml file similar to other phys * Drop ipq5332 specific pcie controllor bindings and reuse ipq9574 pcie controller bindings for ipq5332 * Please see patches for specific changes * Set GPL license for phy-qcom-uniphy-pcie-28lp.c v2: Address review comments from V1 Drop the 'required clocks' change that would break ABI (in dt-binding, dts, gcc-ipq5332.c) Include phy driver from the dependent series v1: https://lore.kernel.org/linux-arm-msm/20231214062847.2215542-1-quic_ipkumar@xxxxxxxxxxx/ Nitheesh Sekar (2): dt-bindings: phy: qcom,uniphy-pcie: Document PCIe uniphy phy: qcom: Introduce PCIe UNIPHY 28LP driver Praveenkumar I (2): arm64: dts: qcom: ipq5332: Add PCIe related nodes arm64: dts: qcom: ipq5332-rdp441: Enable PCIe phys and controllers Varadarajan Narayanan (1): dt-bindings: PCI: qcom: Reuse 'pcie-sdx55' reg bindings for ipq9574 .../devicetree/bindings/pci/qcom,pcie.yaml | 2 +- .../phy/qcom,ipq5332-uniphy-pcie-phy.yaml | 82 +++++ arch/arm64/boot/dts/qcom/ipq5332-rdp441.dts | 74 +++++ arch/arm64/boot/dts/qcom/ipq5332.dtsi | 212 +++++++++++- drivers/phy/qualcomm/Kconfig | 12 + drivers/phy/qualcomm/Makefile | 1 + .../phy/qualcomm/phy-qcom-uniphy-pcie-28lp.c | 302 ++++++++++++++++++ 7 files changed, 682 insertions(+), 3 deletions(-) create mode 100644 Documentation/devicetree/bindings/phy/qcom,ipq5332-uniphy-pcie-phy.yaml create mode 100644 drivers/phy/qualcomm/phy-qcom-uniphy-pcie-28lp.c base-commit: d93148783aea8864ff0a4812324e1657e8e8a686 -- 2.34.1
