|
USB-OTG peripheral features a DRVVBUS signal, which controls the VBUS voltage. The DRVVBUS signal can be
|
|
either internally connected to a PHY (if a PHY supports it), in such a case the PHY would be controlling
|
|
the VBUS voltage by itself. Or the DRVVBUS can be handled by an external logic (a transistor switch).
|
|
Our PHY does not support the DRVVBUS signal, thus we must use an external logic to control the VBUS
|
|
voltage. The DRVVBUS signal is controlled via HCD_PORT_CMD_POWER_OFF and HCD_PORT_CMD_POWER_ON

GPIO number, that will be internally connected to the DRVVBUS signal.

|
USB Host CI target runners feature an external power switch controlled by this GPIO, to control the VBUS
|
|
voltage of USB devices during test.
