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" - reg : contain the offset and length of the system configuration registers used as glue logic to control & parameter phy - reg-names : the names of the system configuration registers in "reg", should be "param" and "reg" - st,syscfg : sysconfig register to manage phy parameter at driver level - 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,sti-powerdown.txt See: Documentation/devicetree/bindings/reset/reset.txt Example: usb2_picophy0: usbpicophy@f8 { compatible = "st,stih407-usb2-phy"; reg = <0xf8 0x04>, /* syscfg 5062 */ <0xf4 0x04>; /* syscfg 5061 */ reg-names = "param", "ctrl"; #phy-cells = <0>; st,syscfg = <&syscfg_core>; resets = <&softreset STIH407_PICOPHY_SOFTRESET>, <&picophyreset STIH407_PICOPHY0_RESET>; reset-names = "global", "port"; };
