From 832f5dacfa0bb081a3b3b979a36a132b28ffacf3 Mon Sep 17 00:00:00 2001 From: Alban Bedel Date: Sun, 2 Aug 2015 18:30:11 +0200 Subject: [PATCH] MIPS: Remove all the uses of custom gpio.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS machines, and each machine type provides its own gpio.h. However only a handful really implement the GPIO API, most just forward everythings to gpiolib. The Alchemy machine is notable as it provides a system to allow implementing the GPIO API at the board level. But it is not used by any board currently supported, so it can also be removed. For most machine types we can just remove the custom gpio.h, as well as the custom wrappers if some exists. Some of the code found in the wrappers must be moved to the respective GPIO driver. A few more fixes are need in some drivers as they rely on linux/gpio.h to provides some machine specific definitions, or used asm/gpio.h instead of linux/gpio.h for the gpio API.
