HI,

	Today on at91 we use gpio != 0 as non valid gpio instead of the
	-EINVAL as define on the gpiolib so we can not use gpio_is_valid to
	check if a gpio is valid

	This patch series update the GPIO base addr to besoc independant and
	the gpio implemetation to start the first gpio as 0 and set -EINVAL
	for a non valid gpio

	So we will be complatible with the other implemenation as the AVR32

	we also update all the drivers

	v3:

	update against at91-next which contains Thomas Petazzoni USB
	support overcurrent notification

Best Regards,
J.
