From 7563bbf89d065a2c3f05059ecbcc805645edcc62 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Sun, 15 Apr 2012 10:52:54 +0100 Subject: gpiolib/arches: Centralise bolierplate asm/gpio.h Rather than requiring architectures that use gpiolib but don't have any need to define anything custom to copy an asm/gpio.h provide a Kconfig symbol which architectures must select in order to include gpio.h and for other architectures just provide the trivial implementation directly. This makes it much easier to do gpiolib updates and is also a step towards making gpiolib APIs available on every architecture. For architectures with existing boilerplate code leave a stub header in place which warns on direct inclusion of asm/gpio.h and includes linux/gpio.h to catch code that's doing this. Direct inclusion of asm/gpio.h has long been deprecated.
