CONFIG_USB_GPIO_VBUS: GPIO based peripheral-only VBUS sensing 'transceiver'

General informations

The Linux kernel configuration item CONFIG_USB_GPIO_VBUS has multiple definitions:

GPIO based peripheral-only VBUS sensing 'transceiver' found in drivers/usb/phy/Kconfig

The configuration item CONFIG_USB_GPIO_VBUS:

Help text

Provides simple GPIO VBUS sensing for controllers with an internal transceiver via the usb_phy interface, and optionally control of a D+ pullup GPIO as well as a VBUS current limit regulator. This driver is for devices that do NOT support role switch. OTG devices that can do role switch (master/peripheral) shall use the USB based connection detection driver USB_CONN_GPIO.

GPIO based peripheral-only VBUS sensing 'transceiver' found in drivers/usb/otg/Kconfig

The configuration item CONFIG_USB_GPIO_VBUS:
