1 ST STiH407 USB PHY controller
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.
7 - compatible : should be "st,stih407-usb2-phy"
8 - reg : contain the offset and length of the system configuration registers
9 used as glue logic to control & parameter phy
10 - reg-names : the names of the system configuration registers in "reg", should be "param" and "reg"
11 - st,syscfg : sysconfig register to manage phy parameter at driver level
12 - resets : list of phandle and reset specifier pairs. There should be two entries, one
13 for the whole phy and one for the port
14 - reset-names : list of reset signal names. Should be "global" and "port"
