[PATCH 0/5] PCI: cadence: Host and EP driver updates for PHY and power management

[Alan Douglas <adouglas@cadence.com>]

This is a series of patches for the cadence PCIe host and EP drivers, to:
 - Add optional list of generic PHYs to host and EP drivers
 - Add PHY bindings to devicetree
 - Add Power Management ops, which will enable/disable PHYs if present
 - Add shutdown handler to host driver
 - Update cdns_pcie_writel function signature

Changes in v3:
	Use devm_phy_optional_get() to get optional PHY
	Updated decription in DT bindings to cover use of single/multiple PHYs
	Split patch to add shutdown callback in separate patch
	Re-based on v4.18-rc1

Changes in v2:
	Split commit into four patches
	Re-based on v4.17-rc1
