1*4882a593SmuzhiyunTI Keystone USB PHY 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunRequired properties: 4*4882a593Smuzhiyun - compatible: should be "ti,keystone-usbphy". 5*4882a593Smuzhiyun - #address-cells, #size-cells : should be '1' if the device has sub-nodes 6*4882a593Smuzhiyun with 'reg' property. 7*4882a593Smuzhiyun - reg : Address and length of the usb phy control register set. 8*4882a593Smuzhiyun 9*4882a593SmuzhiyunThe main purpose of this PHY driver is to enable the USB PHY reference clock 10*4882a593Smuzhiyungate on the Keystone SOC for both the USB2 and USB3 PHY. Otherwise it is just 11*4882a593Smuzhiyunan NOP PHY driver. Hence this node is referenced as both the usb2 and usb3 12*4882a593Smuzhiyunphy node in the USB Glue layer driver node. 13*4882a593Smuzhiyun 14*4882a593Smuzhiyunusb_phy: usb_phy@2620738 { 15*4882a593Smuzhiyun compatible = "ti,keystone-usbphy"; 16*4882a593Smuzhiyun #address-cells = <1>; 17*4882a593Smuzhiyun #size-cells = <1>; 18*4882a593Smuzhiyun reg = <0x2620738 32>; 19*4882a593Smuzhiyun}; 20
