13*833e5d42SEmmanuel Vadotdescription:
14*833e5d42SEmmanuel Vadot  The main purpose of this PHY driver is to enable the USB PHY reference clock
15*833e5d42SEmmanuel Vadot  gate on the Keystone SOC for both the USB2 and USB3 PHY. Otherwise it is just
16*833e5d42SEmmanuel Vadot  an NOP PHY driver. Hence this node is referenced as both the usb2 and usb3
17*833e5d42SEmmanuel Vadot  phy node in the USB Glue layer driver node.
