The code is ported from downstream Codeaurora v5.4 kernel. The main difference from downstream code is the split of PCIe registers configuration from .init to .post_init, since it requires phy_power_on(). Tested on IPQ6010 based hardware. Changes in v7: * Use FIELD_PREP for power limit and scale fields * Add Stanimir Varbanov to Cc * Rebase on v5.19-rc1 Changes in v6: * Drop DT patch applied to the qcom tree * Normalize driver changes subject line * Add a preparatory patch to rename PCIE_CAP_LINK1_VAL to PCIE_CAP_SLOT_VAL, and define it using PCI_EXP_SLTCAP_* macros * Drop a vague comment about ASPM configuration * Add a comment about the source of delay periods Changes in v5: * Remove comments from qcom_pcie_init_2_9_0() (Bjorn Andersson) Changes in v4: * Drop applied DT bits * Add max-link-speed that was missing from the applied v2 patch * Rebase the driver on v5.16-rc3 Changes in v3: * Drop applied patches * Rely on generic code for speed setup * Drop unused macros * Formatting fixes Changes in v2: * Add patch moving GEN3_RELATED macros to a common header * Drop ATU configuration from pcie-qcom * Remove local definition of common registers * Use bulk clk and reset APIs * Remove msi-parent from device-tree Baruch Siach (2): PCI: dwc: tegra: move GEN3_RELATED DBI register to common header PCI: qcom: Define slot capabilities using PCI_EXP_SLTCAP_* Selvam Sathappan Periakaruppan (1): PCI: qcom: Add IPQ60xx support drivers/pci/controller/dwc/pcie-designware.h | 7 + drivers/pci/controller/dwc/pcie-qcom.c | 157 ++++++++++++++++++- drivers/pci/controller/dwc/pcie-tegra194.c | 6 - 3 files changed, 162 insertions(+), 8 deletions(-)
