From 01464226ac6089bd6a33f9899cc792c2355ebf39 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Tue, 28 Aug 2012 13:06:41 -0500 Subject: ARM: make mach/gpio.h headers optional 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.
