   3 This file documents the dt bindings for the usb picoPHY driver which is the PHY for both USB2 and USB3
   4 host controllers (when controlling usb2/1.1 devices) available on STiH407 SoC family from STMicroelectronics.

   6 Required properties:
   7 - compatible            : should be "st,stih407-usb2-phy"
   8 - st,syscfg             : phandle of sysconfig bank plus integer array containing phyparam and phyctrl register offsets
   9 - resets                : list of phandle and reset specifier pairs. There should be two entries, one
  10                           for the whole phy and one for the port
  11 - reset-names           : list of reset signal names. Should be "global" and "port"
