Changes in v13:
- Rebase on pci/next
- Replace access to dev->pins->init_state by new
pinctrl_pm_select_init_state().
- Document pinctrl PM state API.
- Group GPIO PERST# de-assertion with PVPERL delay. (Bjorn)
Changes in v12:
Fix warning reported by kernel test robot <lkp@xxxxxxxxx>
Changes in v11:
Address comments from Manivanna:
- RC driver: Do not call pm_runtime_get_noresume in probe
More uses of dev_err_probe
- EP driver: Use level triggered PERST# irq
Changes in v10:
- Update pcie_ep bindings with dbi2 and atu regs,
thus remove Reviewed-by and Acked-by.
Changes in v9:
- Describe atu and dbi2 shadowed registers in pcie_ep node
Address RC and EP drivers comments from Manivanna:
- Use dev_error_probe() for pm_runtime_enable() calls
- Reword Kconfig help message
- Move pm_runtime_get_noresume() before devm_pm_runtime_enable()
Changes in v8:
- Whitespace in comment
Changes in v7:
- Use device_init_wakeup to enable wakeup
- Fix comments (Bjorn)
Changes in v6:
- Call device_wakeup_enable() to fix WAKE# wakeup.
Address comments from Manivanna:
- Fix/Add Comments
- Fix DT indents
- Remove dw_pcie_ep_linkup() in EP start link
- Add PCIE_T_PVPERL_MS delay in RC PERST# deassert
Changes in v5:
Address driver comments from Manivanna:
- Use dw_pcie_{suspend/resume}_noirq instead of private ones.
- Move dw_pcie_host_init() to probe
- Add stm32_remove_pcie_port cleanup function
- Use of_node_put in stm32_pcie_parse_port
- Remove wakeup-source property
- Use generic dev_pm_set_dedicated_wake_irq to support wake# irq
Changes in v4:
Address bindings comments Rob Herring
- Remove phy property form common yaml
- Remove phy-name property
- Move wake_gpio and reset_gpio to the host root port
Changes in v3:
Address comments from Manivanna, Rob and Bjorn:
- Move host wakeup helper to dwc core (Mani)
- Drop num-lanes=<1> from bindings (Rob)
- Fix PCI address of I/O region (Mani)
- Moved PHY to a RC rootport subsection (Bjorn, Mani)
- Replaced dma-limit quirk by dma-ranges property (Bjorn)
- Moved out perst assert/deassert from start/stop link (Mani)
- Drop link_up test optim (Mani)
- DT and comments rephrasing (Bjorn)
- Add dts entries now that the combophy entries has landed
- Drop delaying Configuration Requests
Changes in v2:
- Fix st,stm32-pcie-common.yaml dt_binding_check
Changes in v1:
Address comments from Rob Herring and Bjorn Helgaas:
- Drop st,limit-mrrs and st,max-payload-size from this patchset
- Remove single reset and clocks binding names and misc yaml cleanups
- Split RC/EP common bindings to a separate schema file
- Use correct PCIE_T_PERST_CLK_US and PCIE_T_RRS_READY_MS defines
- Use .remove instead of .remove_new
- Fix bar reset sequence in EP driver
- Use cleanup blocks for error handling
- Cosmetic fixes
