Qualcomm DWC3 HS AND SS PHY CONTROLLER
--------------------------------------
DWC3 PHY nodes are defined to describe on-chip Synopsis Physical layer
controllers. Each DWC3 PHY controller should have its own node.
Required properties:
- compatible: should contain one of the following:
- "qcom,dwc3-hs-usb-phy" for High Speed Synopsis PHY controller
- "qcom,dwc3-ss-usb-phy" for Super Speed Synopsis PHY controller
- reg: offset and length of the DWC3 PHY controller register set
- #phy-cells: must be zero
- clocks: a list of phandles and clock-specifier pairs, one for each entry in
clock-names.
- clock-names: Should contain "ref" for the PHY reference clock
Optional clocks:
"xo" External reference clock
Example:
phy@100f8800 {
compatible = "qcom,dwc3-hs-usb-phy";
reg = <0x100f8800 0x30>;
clocks = <&gcc USB30_0_UTMI_CLK>;
clock-names = "ref";
#phy-cells = <0>;
status = "ok";
};
phy@100f8830 {
compatible = "qcom,dwc3-ss-usb-phy";
reg = <0x100f8830 0x30>;
clocks = <&gcc USB30_0_MASTER_CLK>;
clock-names = "ref";
#phy-cells = <0>;
status = "ok";
};
