This node defines a regulator used to control the direction of VBUS voltage.

|
|
Specifically whether to supply voltage to VBUS for host mode operation of the OTG port,
|
||
|
|
or allow input voltage from external VBUS for charging. In the hardware, the supply for
|
||
|
|
this regulator comes from usb_otg_in-supply.
