3ffc9cebb6 gpio/sodaville: Convert sodaville driver to new irqdomain API
The irqdomain api changed significantly in v3.4 which caused a build
failure for this driver.

7bf97e1d5a GPIO changes for v3.4
Primarily gpio device driver changes with some minor side effects
 under arch/arm and arch/x86.  Also includes a few core changes such as
 explicitly supporting (electrical) open source and open drain outputs
 and some help for parsing gpio devicetree properties.

8194c7c4d5 gpio/sodaville: Mark broken due to core irqdomain migration
The sodaville driver doesn't build anymore due to the transition to
common irq_domain in the core code.  It needs to be reworked, but
the rework isn't trivial.  Since this is a new driver anyway for
v3.4, mark it as broken now and a fixup patch can re-enable it when
the rework change has been tested.

6518bb69f4 gpio: Move GE GPIO driver to reside within GPIO subsystem
The GE GPIO driver provides basic support (set direction, read/write state)
for the GPIO provided on some GE single board computers. This patch moves
the driver from the 86xx specific platform directrory to the GPIO subsystem
so that it can be used on non-86xx boards.

b43ab901d6 gpio: Add a driver for Sodaville GPIO controller
Sodaville has GPIO controller behind the PCI bus. To my suprissed it is
not the same as on PXA.

The interrupt & gpio chip can be referenced from the device tree like
from any other driver. Unfortunately the driver which uses the gpio
interrupt has to use irq_of_parse_and_map() instead of
platform_get_irq(). The problem is that the platform device (which is
created from the device tree) is most likely created before the
interrupt chip is registered and therefore irq_of_parse_and_map() fails.

In theory the driver works as module. In reality most of the irq
functions are not exported to modules and it is possible that _this_
module is unloaded while the provided irqs are still in use.

265fe02b6f gpio/it8761e: Restrict it8761e gpio driver to x86.
This driver does an unconditional read of io space during module init which
causes a bad dereference on ARM.  It looks to me like this is an x86 only
drivers, so restrict it to only compile on x86.

Convert the pl061 irq_chip code to use the generic irq chip code.

This has the side effect of using 32-bit accesses rather than 8-bit
accesses to interrupt registers. The h/w TRM and testing seem to indicate
this is fine.

8a0a8e8e42 mfd: remove CONFIG_MFD_SUPPORT
We currently have two symbols to control compilation the MFD subsystem,
MFD_SUPPORT and MFD_CORE. The MFD_SUPPORT is actually not required
at all, it only hides the submenu when not set, with the effect that
Kconfig warns about missing dependencies when another driver selects
an MFD driver while MFD_SUPPORT is disabled. Turning the MFD submenu
back from menuconfig into a plain menu simplifies the Kconfig syntax
for those kinds of users and avoids the surprise when the menu
suddenly appears because another driver was enabled that selects this
symbol.

c68308dd50 gpio: move mpc8xxx/512x gpio driver to drivers/gpio
Move the driver to the place where it is expected to be nowadays. Also
rename its CONFIG-name to match the rest and adapt the defconfigs.
Finally, move selection of REQUIRE_GPIOLIB or WANTS_OPTIONAL_GPIOLIB to
the platforms, because this option is per-platform and not per-driver.

1b39d5f2cc gpio/samsung: gpio-samsung.c to support Samsung GPIOs
This patch adds support for Samsung GPIOs with one gpio driver
and removes old GPIO drivers which are drivers/gpio-s3c24xx.c,
gpio-s3c64xx.c, gpio-s5p64x0.c, gpio-s5pc100.c, gpio-s5pv210.c,
gpio-exynos4.c, gpio-plat-samsung.c, plat-samsung/gpio-config.c
and gpio.c to support each Samsung SoCs before. Because the
gpio-samsung.c can replace old Samsung GPIO drivers.
Basically, the gpio-samsung.c has been made by their merging
and removing duplicated definitions.

Note: gpio-samsung.c includes some SoC dependent codes and it
will be replaced next time.

cc890cd78a 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.

752ad5e82d mcp23s08: add i2c support
Add i2c bindings for the mcp230xx devices. This is quite a lot simpler
than the spi one as there's no funky sub addressing done (one struct
i2c_client per struct gpio_chip).

The mcp23s08_platform_data structure is reused for i2c, even though
only a single mcp23s08_chip_info structure is needed.

To use, simply fill out a platform_data structure and pass it in
i2c_board_info, E.G.:

static const struct mcp23s08_platform_data mcp23017_data = {
	.chip[0] = {
		.pullups = 0x00ff,
	},
	.base = 240,
};

static struct i2c_board_info __initdata i2c_devs[] = {
	{ I2C_BOARD_INFO("mcp23017", 0x20),
	  .platform_data = &smartview_mcp23017_data, },
	...
};
