Subject: ARM: gpio: at91: remove redundant include of mach/gpio.h

asm/gpio.h already directly includes mach/gpio.h.

Subject: ARM: gpio: convert includes of mach/gpio.h and asm/gpio.h to
 linux/gpio.h

Convert arch/arm includes of mach/gpio.h and asm/gpio.h to linux/gpio.h
before we start consolidating the individual platform implementations
of the gpio header files.

From 22fe67837614469f8e86c97e9e43d46270701b33 Mon Sep 17 00:00:00 2001
From: Russell King <rmk+kernel@arm.linux.org.uk>

Subject: ARM: gpio: consolidate trivial gpiolib implementations

Consolidate 24 trivial gpiolib implementions out of mach/gpio.h
into asm/gpio.h.  This is basically the include of asm-generic/gpio.h
and the definition of gpio_get_value, gpio_set_value, and gpio_cansleep
as described in Documentation/gpio.txt

From 01e7dc89d060413fd639635618de506093730964 Mon Sep 17 00:00:00 2001
From: Russell King <rmk+kernel@arm.linux.org.uk>
Date: Tue, 26 Jul 2011 11:29:42 +0100
Subject: ARM: gpio: consolidate gpio_to_irq

Many of the gpio_to_irq implementations use the gpiolib version of this
function.  Provide the standard gpiolib gpio_to_irq() for everyone, but
allow platforms to override it if they wish.  Add the neccessary
overrides for those platforms which do not use the standard definition.

From 8f3c4537bb08001c4772d66ad3fcfcf24d8d180d Mon Sep 17 00:00:00 2001
From: Russell King <rmk+kernel@arm.linux.org.uk>
Date: Mon, 8 Aug 2011 13:58:28 +0100
Subject: ARM: gpio: make trivial GPIOLIB implementation the default

Rather than marking the mach/gpio.h header files which want to use the
trivial GPIOLIB implementation, mark those which do not want to use it
instead.  This means that by default, you get the trivial implementation
and only have to do something extra if you need to.  This should
encourage the use of the trivial default implementation.

As an additional bonus, several gpio.h header files become empty.

Subject: ARM: 7032/1: plat-nomadik: break out GPIO driver specifics

The <[plat|mach]/gpio.h> file is included from upper directories
and deal with generic GPIO and gpiolib stuff. Break out the
platform and driver specific defines and functions into its own
header file.

Subject: ARM: 7033/1: mach-u300: break out GPIO driver specifics

The <mach/gpio.h> file is included from upper directories
and deal with generic GPIO and gpiolib stuff. Break out the
platform and driver specific defines and functions into its own
header file.

Subject: ARM: 7034/1: mach-u300: delete irq_to_gpio() function

This function is not used in the U300 build, and on the whole the
call is hard to consolidate so get rid of it from this machine.

Subject: ARM: 7036/1: mach-ks8695: break out GPIO driver specifics

The <mach/gpio.h> file is included from upper directories
and deal with generic GPIO and gpiolib stuff. Break out the
platform and driver specific defines and functions into its own
header file.

Subject: ARM: 7037/1: mach-ks8695: fix GPIO LEDs

Enabling the LEDs on the ks8695 doesn't even compile, fix it with
a proper include and also replace a <mach/gpio.h> with the proper
<linux/gpio.h>.

Subject: ARM: 7039/1: mach-davinci: move DaVinci TNET GPIO driver to GPIO
 subsystem

As per example from the other ARM boards, push the DaVinci TNET
GPIO driver down to the GPIO subsystem so it can be consolidated.

Subject: ARM: 7040/1: mach-davinci: break out GPIO driver specifics

The <mach/gpio.h> file is included from upper directories
and deal with generic GPIO and gpiolib stuff. Break out the
platform and driver specific defines and functions into its own
header file.

hooking up the callback in the driver and using __gpio_to_irq.

Subject: ARM: 7043/1: mach-ixp2000: rename GPIO header

The ixp2000 abuses the <mach/gpio.h> namespace by not implementing
any generic GPIO nor gpiolib functions in it - just custom GPIO.
Rename the header to <mach/gpio-ixp2000.h> for clarity.

Subject: ARM: 7045/1: mach-lpc32xx: break out GPIO driver specifics

The <mach/gpio.h> file is included from upper directories
and deal with generic GPIO and gpiolib stuff. Break out the
platform and driver specific defines and functions into its own
header file.

Subject: ARM: 7050/1: mach-sa1100: delete irq_to_gpio() function

This function is not used in the assabet build, and on the whole the
call is hard to consolidate so get rid of it from this machine.

From a1e6b41e8ec152efceb3128592b83d40c8a28334 Mon Sep 17 00:00:00 2001
From: Linus Walleij <linus.walleij@linaro.org>
Date: Tue, 23 Aug 2011 12:51:24 +0100
Subject: ARM: 7057/1: mach-pnx4008: rename GPIO header

The PNX4008 header file is using the generic gpio and gpiolib
namespace in <mach/gpio.h> yet the GPIO interface is not generic
at all so rename it to <mach/gpio-pnx4008.h>

This fixes a build failure in current -next: the includes were
changed from <mach/gpio.h> to <linux/gpio.h> but since this
platform isn't using generic gpio <linux/gpio.h> did not include
<mach/gpio.h> and things broke apart.

Subject: ARM: 7054/1: arm/tegra: Delete custom gpio_to_irq, and irq_to_gpio

By not definining a custom gpio_to_irq, the default gpiolib version is
used, allowing platform consolidation.

irq_to_gpio is deprecated and in the process of being removed. Make that
happen now for ARM Tegra.

This also partially fixes the Tegra build; it was broken because gpio.h
referred to EINVAL, which wasn't always defined when <mach/gpio.h> was
included.

Subject: ARM: 7083/1: rewrite U300 GPIO to use gpiolib

This rewrites the U300 GPIO so as to use gpiolib and
struct gpio_chip instead of just generic GPIO, hiding
all the platform specifics and passing in GPIO chip
variant as platform data at runtime instead of the
compiletime kludges.

As a result <mach/gpio.h> is now empty for U300 and
using just defaults.

The <mach/gpio.h> file is included from upper directories
and deal with generic GPIO and gpiolib stuff. Break out the
platform and driver specific defines and functions into its own
header file.

Subject: ARM: 7103/1: plat-pxa: move PXA GPIO driver to GPIO subsystem

As per example from the other ARM boards, push the PXA
GPIO driver down to the GPIO subsystem so it can be consolidated.

Subject: ARM: 7104/1: plat-pxa: break out GPIO driver specifics

The <mach/gpio.h> file is included from upper directories
and deal with generic GPIO and gpiolib stuff. Break out the
platform and driver specific defines and functions into its own
header file.

Subject: ARM: 7135/1: ep93xx: bring back missing <mach/gpio.h>

Change bd5f12a2476 (ARM: 7042/3: mach-ep93xx: break out GPIO driver specifics)
accidentally removed the ep93xx <mach/gpio.h> instead of making it an empty
file. This causes compilation to fail:

In file included from include/linux/gpio.h:18:0,
                  from drivers/gpio/gpiolib.c:10:
linux/arch/arm/include/asm/gpio.h:5:23: fatal error: mach/gpio.h: No such file or directory
compilation terminated.
make[2]: *** [drivers/gpio/gpiolib.o] Error 1

Fix this by adding the file back.
