-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"
-See: Documentation/devicetree/bindings/reset/st,stih407-powerdown.yaml
-See: Documentation/devicetree/bindings/reset/reset.txt
-
-Example:
-
-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";
-};
