1ST STiH407 USB PHY controller
2
3This file documents the dt bindings for the usb picoPHY driver which is the PHY for both USB2 and USB3
4host controllers (when controlling usb2/1.1 devices) available on STiH407 SoC family from STMicroelectronics.
5
6Required 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"
