Subject: [GIT PULL] GPIO bulk changes for v3.13
Hi Linus,
here is the bulk of GPIO changes for the v3.13 development
cycle.
Most of the description is in the signed tag. 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/
I merged in -rc4 and -rc6 to get rid of some nasty conflicts
appearing during the v3.12 development cycle.
Please pull it in!
Yours,
Linus Walleij

gpio: gpio-mxs: Remove unneeded dt checks (2013-11-06 10:51:24 +0100)
----------------------------------------------------------------
GPIO bulk changes for the v3.13 development cycle
- 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.
