[PATCH] PCI: dra7xx: Invoke phy_set_mode API to set PHY mode to PHY_MODE_PCIE

From: Kishon Vijay Abraham I
Date: Thu Jan 24 2019 - 05:46:18 EST


Certain PHYs used with PCIe controller can also be used with other
controllers such as USB or SATA. In order to configure the PHY
to work with PCIe controller, invoke phy_set_mode API with mode
set to PHY_MODE_PCIE.
