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. 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): PCIe: qcom: change duplicate PCI reset to phy reset Ansuel Smith (7): PCIe: qcom: add missing ipq806x clocks in PCIe driver devicetree: bindings: pci: add missing clks to qcom,pcie PCIe: qcom: Fixed pcie_phy_clk branch issue PCIe: qcom: add missing reset for ipq806x devicetree: bindings: pci: add ext reset to qcom,pcie PCIe: qcom: fix init problem with missing PARF programming devicetree: bindings: pci: add ipq8064 rev 2 variant to qcom,pcie Sham Muthayyan (2): PCIe: qcom: add ipq8064 rev2 variant and set tx term offset PCIe: qcom: add Force GEN1 support .../devicetree/bindings/pci/qcom,pcie.txt | 56 +++++++- drivers/pci/controller/dwc/pcie-qcom.c | 134 +++++++++++++++--- 2 files changed, 167 insertions(+), 23 deletions(-)
