0001 Lantiq XWAY SoC RCU USB 1.1/2.0 PHY binding
0002 ===========================================
0003
0004 This binding describes the USB PHY hardware provided by the RCU module on the
0005 Lantiq XWAY SoCs.
0006
0007 This node has to be a sub node of the Lantiq RCU block.
0008
0009 -------------------------------------------------------------------------------
0010 Required properties (controller (parent) node):
0011 - compatible : Should be one of
0012 "lantiq,ase-usb2-phy"
0013 "lantiq,danube-usb2-phy"
0014 "lantiq,xrx100-usb2-phy"
0015 "lantiq,xrx200-usb2-phy"
0016 "lantiq,xrx300-usb2-phy"
0017 - reg : Defines the following sets of registers in the parent
0018 syscon device
0019 - Offset of the USB PHY configuration register
0020 - Offset of the USB Analog configuration
0021 register (only for xrx200 and xrx200)
0022 - clocks : References to the (PMU) "phy" clk gate.
0023 - clock-names : Must be "phy"
0024 - resets : References to the RCU USB configuration reset bits.
0025 - reset-names : Must be one of the following:
0026 "phy" (optional)
0027 "ctrl" (shared)
0028

0030 Example for the USB PHYs on an xRX200 SoC:
0031 usb_phy0: usb2-phy@18 {
0032 compatible = "lantiq,xrx200-usb2-phy";
0033 reg = <0x18 4>, <0x38 4>;
0034
0035 clocks = <&pmu PMU_GATE_USB0_PHY>;
0036 clock-names = "phy";
0037 resets = <&reset1 4 4>, <&reset0 4 4>;
0038 reset-names = "phy", "ctrl";
0039 #phy-cells = <0>;
0040 };
