18c2ecf20Sopenharmony_ciTI Keystone USB PHY 28c2ecf20Sopenharmony_ci 38c2ecf20Sopenharmony_ciRequired properties: 48c2ecf20Sopenharmony_ci - compatible: should be "ti,keystone-usbphy". 58c2ecf20Sopenharmony_ci - #address-cells, #size-cells : should be '1' if the device has sub-nodes 68c2ecf20Sopenharmony_ci with 'reg' property. 78c2ecf20Sopenharmony_ci - reg : Address and length of the usb phy control register set. 88c2ecf20Sopenharmony_ci 98c2ecf20Sopenharmony_ciThe main purpose of this PHY driver is to enable the USB PHY reference clock 108c2ecf20Sopenharmony_cigate on the Keystone SOC for both the USB2 and USB3 PHY. Otherwise it is just 118c2ecf20Sopenharmony_cian NOP PHY driver. Hence this node is referenced as both the usb2 and usb3 128c2ecf20Sopenharmony_ciphy node in the USB Glue layer driver node. 138c2ecf20Sopenharmony_ci 148c2ecf20Sopenharmony_ciusb_phy: usb_phy@2620738 { 158c2ecf20Sopenharmony_ci compatible = "ti,keystone-usbphy"; 168c2ecf20Sopenharmony_ci #address-cells = <1>; 178c2ecf20Sopenharmony_ci #size-cells = <1>; 188c2ecf20Sopenharmony_ci reg = <0x2620738 32>; 198c2ecf20Sopenharmony_ci}; 20
