1TI Keystone USB PHY 2 3Required properties: 4 - compatible: should be "ti,keystone-usbphy". 5 - #address-cells, #size-cells : should be '1' if the device has sub-nodes 6 with 'reg' property. 7 - reg : Address and length of the usb phy control register set. 8 9The main purpose of this PHY driver is to enable the USB PHY reference clock 10gate on the Keystone SOC for both the USB2 and USB3 PHY. Otherwise it is just 11an NOP PHY driver. Hence this node is referenced as both the usb2 and usb3 12phy node in the USB Glue layer driver node. 13 14usb_phy: usb_phy@2620738 { 15 compatible = "ti,keystone-usbphy"; 16 #address-cells = <1>; 17 #size-cells = <1>; 18 reg = <0x2620738 32>; 19}; 20
