- 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.

Merge tag 'gpio-v3.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
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.

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
