TI Keystone USB PHY
|
|
|
|
Required properties:
|
|
- compatible: should be "ti,keystone-usbphy".
|
|
- #address-cells, #size-cells : should be '1' if the device has sub-nodes
|
|
with 'reg' property.
|
|
- reg : Address and length of the usb phy control register set.
|
|
|
|
The main purpose of this PHY driver is to enable the USB PHY reference clock
|
|
gate on the Keystone SOC for both the USB2 and USB3 PHY. Otherwise it is just
|
|
an NOP PHY driver. Hence this node is referenced as both the usb2 and usb3
|
|
phy node in the USB Glue layer driver node.

usb_phy: usb_phy@2620738 {
|

compatible = "ti,keystone-usbphy";
|

#address-cells = <1>;
|
|
#size-cells = <1>;
|
|
reg = <0x2620738 32>;

status = "disabled";

};
