bool	gpio_vbus_inverted
bool	gpio_pullup_inverted
bool	wakeup

Detailed Description

struct gpio_vbus_mach_info - configuration for gpio_vbus : VBUS sensing GPIO : optional D+ or D- pullup GPIO (else negative/invalid) : true if gpio_vbus is active low : true if gpio_pullup is active low : configure gpio_vbus as a wake-up source

The VBUS sensing GPIO should have a pulldown, which will normally be part of a resistor ladder turning a 4.0V-5.25V level on VBUS into a value the GPIO detects as active. Some systems will use comparators.
