extcon: usb-gpio: register extcon device before IRQ registration

2015-04-27T02:06:05Z

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. Signed-off-by: Robert Baldyga Acked-by: Roger Quadros Signed-off-by: Chanwoo Choi

extcon: usb-gpio: Introduce gpio usb extcon driver

2015-02-24T00:00:53Z

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.
