USB COMPARATOR OF TWL CHIPS
|
|
|
|
TWL6030 USB COMPARATOR
|
|
- compatible : Should be "ti,twl6030-usb"
|
|
- interrupts : Two interrupt numbers to the cpu should be specified. First
|
|
interrupt number is the otg interrupt number that raises ID interrupts when
|
|
the controller has to act as host and the second interrupt number is the
|
|
usb interrupt number that raises VBUS interrupts when the controller has to
|
|
act as device
|
|
- usb-supply : phandle to the regulator device tree node. It should be vusb
|
|
if it is twl6030 or ldousb if it is twl6032 subclass.
|
|
|
|
twl6030-usb {
|
|
compatible = "ti,twl6030-usb";
|
|
interrupts = < 4 10 >;
|

};

TWL4030 USB PHY AND COMPARATOR
|
|
- compatible : Should be "ti,twl4030-usb"
|
|
- interrupts : The interrupt numbers to the cpu should be specified. First
|
|
interrupt number is the otg interrupt number that raises ID interrupts
|
|
and VBUS interrupts. The second interrupt number is optional.
|
|
- <supply-name>-supply : phandle to the regulator device tree node.
|
|
<supply-name> should be vusb1v5, vusb1v8 and vusb3v1
|
|
- usb_mode : The mode used by the phy to connect to the controller. "1"
|
|
specifies "ULPI" mode and "2" specifies "CEA2011_3PIN" mode.
|
|
|
|
If a sibling node is compatible "ti,twl4030-bci", then it will find
|
|
this device and query it for USB power status.
