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.

Community interest - https://lore.kernel.org/linux-arm-msm/20240310132915.GE3390@thinkpad/ v5: phy bindings: * Drop '3x1' & '3x2' from compatible string * Use 'num-lanes' to differentiate instead of '3x1' or '3x2' in compatible string * Describe clocks and resets instead of just maxItems phy driver: * Get num-lanes from DTS * Drop compatible specific init data as there is only one compatible string controller bindings: * Re-arrange 5332 and 9574 compatibles to handle fallback usage in dts dtsi: * Add 'num-lanes' to "pcie1_phy: phy@4b1000" * Make ipq5332 as main and ipq9574 as fallback compatible * Sort controller nodes per address misc: Add R-B tag from Konrad to dts and dtsi patches v4: * phy bindings - Create ipq5332 compatible instead of reusing ipq9574 for bindings * phy bindings - Remove reset-names as the resets are handled with bulk APIs * phy bindings - Fix order in the 'required' section * phy bindings - Remove clock-output-names * dtsi - Add missing reset for pcie1_phy * dtsi - Convert 'reg-names' to a vertical list * dts - Fix nodes sort order * dts - Use property-n followed by property-names 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: Document the IPQ5332 PCIe controller .../devicetree/bindings/pci/qcom,pcie.yaml | 10 +- .../phy/qcom,ipq5332-uniphy-pcie-phy.yaml | 71 +++++ arch/arm64/boot/dts/qcom/ipq5332-rdp441.dts | 76 +++++ arch/arm64/boot/dts/qcom/ipq5332.dtsi | 221 +++++++++++++- drivers/phy/qualcomm/Kconfig | 12 + drivers/phy/qualcomm/Makefile | 1 + .../phy/qualcomm/phy-qcom-uniphy-pcie-28lp.c | 287 ++++++++++++++++++ 7 files changed, 674 insertions(+), 4 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: 8155b4ef3466f0e289e8fcc9e6e62f3f4dceeac2 -- 2.34.1
