1Lantiq XWAY SoC RCU USB 1.1/2.0 PHY binding 2=========================================== 3 4This binding describes the USB PHY hardware provided by the RCU module on the 5Lantiq XWAY SoCs. 6 7This node has to be a sub node of the Lantiq RCU block. 8 9------------------------------------------------------------------------------- 10Required properties (controller (parent) node): 11- compatible : Should be one of 12 "lantiq,ase-usb2-phy" 13 "lantiq,danube-usb2-phy" 14 "lantiq,xrx100-usb2-phy" 15 "lantiq,xrx200-usb2-phy" 16 "lantiq,xrx300-usb2-phy" 17- reg : Defines the following sets of registers in the parent 18 syscon device 19 - Offset of the USB PHY configuration register 20 - Offset of the USB Analog configuration 21 register (only for xrx200 and xrx200) 22- clocks : References to the (PMU) "phy" clk gate. 23- clock-names : Must be "phy" 24- resets : References to the RCU USB configuration reset bits. 25- reset-names : Must be one of the following: 26 "phy" (optional) 27 "ctrl" (shared) 28 29------------------------------------------------------------------------------- 30Example for the USB PHYs on an xRX200 SoC: 31 usb_phy0: usb2-phy@18 { 32 compatible = "lantiq,xrx200-usb2-phy"; 33 reg = <0x18 4>, <0x38 4>; 34 35 clocks = <&pmu PMU_GATE_USB0_PHY>; 36 clock-names = "phy"; 37 resets = <&reset1 4 4>, <&reset0 4 4>; 38 reset-names = "phy", "ctrl"; 39 #phy-cells = <0>; 40 };
