Some optional reset and clocks were missing. Fix a problem with no PARF programming that cause kernel lock on load. Add support to force gen 1 speed if needed. (due to hardware limitation) Add ipq8064 rev 2 support that use a different tx termination offset. v3: * Fix check reported by checkpatch --strict * Rename force_gen1 to gen * Fix spelling error * Better describe qcom_clear_and_set_dword * Make PARF deemph and equalization configurable v2: * Drop iATU programming (already done in pcie init) * Use max-link-speed instead of force-gen1 custom definition * Drop MRRS to 256B (Can't find a realy reason why this was suggested) * Introduce a new variant for different revision of ipq8064 Abhishek Sahu (1): PCI: qcom: change duplicate PCI reset to phy reset Ansuel Smith (8): PCI: qcom: add missing ipq806x clocks in PCIe driver devicetree: bindings: pci: add missing clks to qcom,pcie PCI: qcom: add missing reset for ipq806x devicetree: bindings: pci: add ext reset to qcom,pcie PCI: qcom: introduce qcom_clear_and_set_dword PCI: qcom: add support for defining some PARF params devicetree: bindings: pci: document PARF params bindings devicetree: bindings: pci: add ipq8064 rev 2 variant to qcom,pcie Sham Muthayyan (2): PCI: qcom: add ipq8064 rev2 variant and set tx term offset PCI: qcom: add Force GEN1 support .../devicetree/bindings/pci/qcom,pcie.txt | 51 +++- drivers/pci/controller/dwc/pcie-qcom.c | 241 ++++++++++++------ 2 files changed, 211 insertions(+), 81 deletions(-)
