Subject: [PATCH 07/10] gpio: move the Nomadik GPIO driver to drivers/gpio
From: Linus Walleij <linus.walleij@...aro.org>
This takes the Nomadik GPIO driver out of the plat-nomadik
directory and pushes it down into drivers/gpio where it belongs.
Signed-off-by: Linus Walleij <linus.walleij@...aro.org>
