0001 ST STiH407 USB PHY controller
0002
0003 This file documents the dt bindings for the usb picoPHY driver which is the PHY for both USB2 and USB3
0004 host controllers (when controlling usb2/1.1 devices) available on STiH407 SoC family from STMicroelectronics.
0005
0006 Required properties:
0007 - compatible            : should be "st,stih407-usb2-phy"
0008 - st,syscfg             : phandle of sysconfig bank plus integer array containing phyparam and phyctrl register offsets
0009 - resets                : list of phandle and reset specifier pairs. There should be two entries, one
0010                           for the whole phy and one for the port
0011 - reset-names           : list of reset signal names. Should be "global" and "port"
