Robert Baldyga	bc1aabad39	extcon: usb-gpio: register extcon device before IRQ registration ... IRQ handler touches info->edev, so if interrupt occurs before extcon device initialization it can cause NULL pointer dereference. Doing extcon initialization before IRQ handler registration fixes this problem.

Roger Quadros	e52817faae	extcon: usb-gpio: Introduce gpio usb extcon driver ... This driver observes the USB ID pin connected over a GPIO and updates the USB cable extcon states accordingly. The existing GPIO extcon driver is not suitable for this purpose as it needs to be taught to understand USB cable states and it can't handle more than one cable per instance. For the USB case we need to handle 2 cable states. 1) USB (attach/detach) 2) USB-HOST (attach/detach) This driver can be easily updated in the future to handle VBUS events in case it happens to be available on GPIO for any platform.
