15 * struct gpio_vbus_mach_info - configuration for gpio_vbus
16 * @gpio_vbus: VBUS sensing GPIO
17 * @gpio_pullup: optional D+ or D- pullup GPIO (else negative/invalid)
18 * @gpio_vbus_inverted: true if gpio_vbus is active low
19 * @gpio_pullup_inverted: true if gpio_pullup is active low
20 * @wakeup: configure gpio_vbus as a wake-up source
21 *
22 * The VBUS sensing GPIO should have a pulldown, which will normally be
23 * part of a resistor ladder turning a 4.0V-5.25V level on VBUS into a
24 * value the GPIO detects as active.  Some systems will use comparators.
