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";
|
|
};
