First 6*4882a593Smuzhiyun interrupt number is the otg interrupt number that raises ID interrupts when 7*4882a593Smuzhiyun the controller has to act as host and the second interrupt number is the 8*4882a593Smuzhiyun usb interrupt number that raises VBUS interrupts when the controller has to 9*4882a593Smuzhiyun act as device 10*4882a593Smuzhiyun - usb-supply : phandle to the regulator device tree node. It should be vusb 11*4882a593Smuzhiyun if it is twl6030 or ldousb if it is twl6032 subclass. 12*4882a593Smuzhiyun 13*4882a593Smuzhiyuntwl6030-usb { 14*4882a593Smuzhiyun compatible = "ti,twl6030-usb"; 15*4882a593Smuzhiyun interrupts = < 4 10 >; 16*4882a593Smuzhiyun}; 17*4882a593Smuzhiyun 18*4882a593SmuzhiyunBoard specific device node entry 19*4882a593Smuzhiyun&twl6030-usb { 20*4882a593Smuzhiyun usb-supply = <&vusb>; 21*4882a593Smuzhiyun}; 22*4882a593Smuzhiyun 23*4882a593SmuzhiyunTWL4030 USB PHY AND COMPARATOR 24*4882a593Smuzhiyun - compatible : Should be "ti,twl4030-usb" 25*4882a593Smuzhiyun - interrupts : The interrupt numbers to the cpu should be specified.
