Pull GPIO changes from Linus Walleij:
"Here is the bulk of GPIO changes for the v3.13 development cycle.

I've got ACKs for the things that affect other subsystems (or it's my
own subsystem, like pinctrl). Most of that pertain to an attempt from
my side to consolidate and get rid of custom GPIO implementations in
the ARM tree. I will continue doing this.

The main change this time is the new GPIO descriptor API, background
for this can be found in Corbet's summary from this january in LWN:

http://lwn.net/Articles/533632/

Summary:

- Merged the GPIO descriptor API from Alexandre Courbot. This is a
first step toward trying to get rid of the global GPIO numberspace
for the future.

- Add an API so that driver can flag that a certain GPIO line is
being used by a irqchip backend for generating IRQs, so that we can
enforce checks, like not allowing users to switch that line to an
output at runtime, since this makes no sense. Implemented
corresponding calls in a few select drivers.

- ACPI GPIO cleanups, refactorings and switch to using the
descriptor-based interface.

- Support for the TPS80036 Palmas GPIO variant.

- A new driver for the Broadcom Kona GPIO SoC IP block.

- Device tree support for the PCF857x driver.

- A set of ARM GPIO refactorings with the goal of getting rid of a
bunch of custom GPIO implementations from the arch/arm/* tree:

* Move the IOP GPIO driver to the GPIO subsystem and fix all users
to use the gpiolib API for accessing GPIOs. Delete the old
custom GPIO implementation.

* Delete the unused custom PXA GPIO implemention.

* Convert all users of the IXP4 custom GPIO implementation to use
gpiolib and delete the custom implementation.

* Delete the custom Gemini GPIO implementation, also completely
unused.

- Various cleanups and renamings"

gpio: pl061: don't depend on CONFIG_ARM

2013-11-06T09:41:38+00:00

The pl061 driver has no real dependency on ARM, so remove the kconfig
dependency.

gpiolib: make GPIO_DEVRES depend on GPIOLIB

2013-10-30T01:26:13+00:00

Current Kconfig allows GPIO_DEVRES to be selected and compiled without
GPIOLIB. This does not make sense anymore since GPIOLIB has become the
exclusive way to deal with GPIOs. This patch makes GPIO_DEVRES available
only if GPIOLIB is selected.

gpio: add TB10x GPIO driver

2013-10-25T21:42:34+00:00

gpio: rename gpio-langwell to gpio-intel-mid

2013-10-11T14:30:47+00:00

gpio-langwell is a deprecated name. Despite the driver was made
initially for Langwell, it supports now other Intel Mid SoC's.

This patch does no change beside the file renaming with Kconfig/Makefile
update.

gpio: ucb1400: Can be built as a module

With the recent code cleanup from Marek Vasut, driver gpio-ucb1400 can
be built as a module, so change symbol GPIO_UCB1400 from bool to
tristate.

These GPIO controllers may contain up to 8 banks where each bank
includes 32 pins that can be driven high or low and act as an edge

emev2: GPIOLIB: Enable support for OF

2013-09-19T13:33:45+00:00

EMEV2 is now a DT platform, however the GPIO driver cannot be used
from a DT file since it does not fill out the of_node field in its
gpio_chip structure.
