[Christian Bruel]

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
