Lantiq XWAY SoC RCU USB 1.1/2.0 PHY binding
|
===========================================
|
|
This binding describes the USB PHY hardware provided by the RCU module on the
|
Lantiq XWAY SoCs.
|
|
This node has to be a sub node of the Lantiq RCU block.
|
|
-------------------------------------------------------------------------------
|
Required properties (controller (parent) node):
|
- compatible : Should be one of
|
"lantiq,ase-usb2-phy"
|
"lantiq,danube-usb2-phy"
|
"lantiq,xrx100-usb2-phy"
|
"lantiq,xrx200-usb2-phy"
|
"lantiq,xrx300-usb2-phy"
|
- reg : Defines the following sets of registers in the parent
|
syscon device
|
- Offset of the USB PHY configuration register
|
- Offset of the USB Analog configuration
|
register (only for xrx200 and xrx200)
|
- clocks : References to the (PMU) "phy" clk gate.
|
- clock-names : Must be "phy"
|
- resets : References to the RCU USB configuration reset bits.
|
- reset-names : Must be one of the following:
|
"phy" (optional)
|
"ctrl" (shared)
|
|
-------------------------------------------------------------------------------
|
Example for the USB PHYs on an xRX200 SoC:
|
usb_phy0: usb2-phy@18 {
|
compatible = "lantiq,xrx200-usb2-phy";
|
reg = <0x18 4>, <0x38 4>;
|
|
clocks = <&pmu PMU_GATE_USB0_PHY>;
|
clock-names = "phy";
|
resets = <&reset1 4 4>, <&reset0 4 4>;
|
reset-names = "phy", "ctrl";
|
#phy-cells = <0>;
|
};
