[PATCH v2 6/6] ARM: make mach/gpio.h headers optional
Rob Herring
robherring2 at gmail.com
Thu Sep 6 15:42:43 EDT 2012
From: Rob Herring <rob.herring at calxeda.com>
Most platforms don't need mach/gpio.h and it prevents multi-platform
kernel images. Add CONFIG_NEED_MACH_GPIO_H and make platforns select it
if they need gpio.h. This is platforms that define __GPIOLIB_COMPLEX
or have lots of implicit includes pulled in by mach/gpio.h.
at91 and omap have gpio clean-up pending and can drop
CONFIG_NEED_MACH_GPIO_H once that is in.
