| 2 | |
| 3 | TWL6030 USB COMPARATOR |
| 4 | - compatible : Should be "ti,twl6030-usb" |
| 5 | - interrupts : Two interrupt numbers to the cpu should be specified. First |
| 6 | interrupt number is the otg interrupt number that raises ID interrupts when |
| 7 | the controller has to act as host and the second interrupt number is the |
| 8 | usb interrupt number that raises VBUS interrupts when the controller has to |
| 9 | act as device |
| 10 | - usb-supply : phandle to the regulator device tree node. It should be vusb |
| 11 | if it is twl6030 or ldousb if it is twl6032 subclass. |
| 12 | |
| 13 | twl6030-usb { |
| 14 | compatible = "ti,twl6030-usb"; |
| 15 | interrupts = < 4 10 >; |
| 16 | }; |
| 17 | |
| 18 | Board specific device node entry |
| 19 | &twl6030-usb { |
| 20 | usb-supply = <&vusb>; |
| 21 | }; |
| 22 | |
| 23 | TWL4030 USB PHY AND COMPARATOR |
| 24 | - compatible : Should be "ti,twl4030-usb" |
| 25 | - interrupts : The interrupt numbers to the cpu should be specified. First |
| 26 | interrupt number is the otg interrupt number that raises ID interrupts |
| 27 | and VBUS interrupts. The second interrupt number is optional. |
| 28 | - <supply-name>-supply : phandle to the regulator device tree node. |
| 29 | <supply-name> should be vusb1v5, vusb1v8 and vusb3v1 |
| 30 | - usb_mode : The mode used by the phy to connect to the controller. "1" |
| 31 | specifies "ULPI" mode and "2" specifies "CEA2011_3PIN" mode. |
| 32 | |
| 33 | If a sibling node is compatible "ti,twl4030-bci", then it will find |
| 34 | this device and query it for USB power status. |
