There are 3 PCIe instances on this SoC each with different PHYs. The PCIe controller and PHYs are mostly comaptible with the ones found on SDM845 SoC, hence the old drivers are modified to add the support. This series has been tested on RB5 board with QCA6390 chipset connected onboard. NOTE: This series functionally depends on the following patch: https://lore.kernel.org/linux-arm-kernel/1599814203-14441-3-git-send-email-hayashi.kunihiko@socionext.com/ I've dropped a similar patch in v2. Thanks, Mani Changes in v3: * Rebased on top of phy/next * Renamed ops_sm8250 to ops_1_9_0 to maintain uniformity Changes in v2: * Fixed the PHY and PCIe bindings * Introduced secondary table in PHY driver to abstract out the common configs. * Used a more generic way of configuring BDF to SID mapping * Dropped ATU change in favor of a patch spotted by Rob Manivannan Sadhasivam (5): dt-bindings: phy: qcom,qmp: Add SM8250 PCIe PHY bindings phy: qcom-qmp: Add SM8250 PCIe QMP PHYs dt-bindings: pci: qcom: Document PCIe bindings for SM8250 SoC PCI: qcom: Add SM8250 SoC support PCI: qcom: Add support for configuring BDF to SID mapping for SM8250 .../devicetree/bindings/pci/qcom,pcie.txt | 6 +- .../devicetree/bindings/phy/qcom,qmp-phy.yaml | 6 + drivers/pci/controller/dwc/Kconfig | 1 + drivers/pci/controller/dwc/pcie-qcom.c | 149 ++++++++++ drivers/phy/qualcomm/phy-qcom-qmp.c | 281 +++++++++++++++++- drivers/phy/qualcomm/phy-qcom-qmp.h | 18 ++ 6 files changed, 455 insertions(+), 6 deletions(-)
