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

|
usb2_picophy0: usbpicophy@f8 {
|
compatible = "st,stih407-usb2-phy";
|
#phy-cells = <0>;
|
st,syscfg = <&syscfg_core 0x100 0xf4>;
|
resets = <&softreset STIH407_PICOPHY_SOFTRESET>,
|
<&picophyreset STIH407_PICOPHY0_RESET>;
|
reset-names = "global", "port";
|
};
