Subject: [GIT PULL] GPIO bulk changes for the v3.18 series
Hi Linus,
here is the bulk of GPIO changes for the v3.18 cycle.
When I tested to pull this into your tree I found two conflicts that
also appeared in linux-next, one in the qualcomm driver which
is trivial and one in the gpiolib.c which is also kind of trivial (lower
hunk is the correct one).
The removal if the return value from gpiochip_remove() hits sites
a bit all over the kernel (showing how this API permeates platforms)
but they are mostly ACKed and have survived linux-next testing.
The feature details are in the tag.
Please pull this in! (And fix the glorious conflicts...)
Yours,
Linus Walleij
The following changes since commit 52addcf9d6669fa439387610bc65c92fa0980cef:

gpio: pch: Build context save/restore only for PM (2014-10-02 16:07:00 +0200)
----------------------------------------------------------------
This is the bulk of GPIO changes for the v3.18 development
cycle:
- Increase the default ARCH_NR_GPIO from 256 to 512. This
was done to avoid having a custom <asm/gpio.h> header for
the x86 architecture - GPIO is custom and complicated
enough as it is already! We want to move to a radix to
store the descriptors going forward, and finally get rid
of this fixed array size altogether.
- Endgame patching of the gpio_remove() semantics initiated
by Abdoulaye Berthe. It is not accepted by the system that
the removal of a GPIO chip fails during e.g. reboot or
shutdown, and therefore the return value has now painfully
been refactored away. For special cases like GPIO expanders
on a hot-pluggable bus like USB, we may later add some
gpiochip_try_remove() call, but for the cases we have now,
return values are moot.
- Some incremental refactoring of the gpiolib core and ACPI
GPIO library for more descriptor usage.
- Refactor the chained IRQ handler set-up method to handle
also threaded, nested interrupts and set up the parent IRQ
correctly. Switch STMPE and TC3589x drivers to use this
registration method.
- Add a .irq_not_threaded flag to the struct gpio_chip, so
that also GPIO expanders that block but are still not
using threaded IRQ handlers.
- New drivers for the ARM64 X-Gene SoC GPIO controller.
- The syscon GPIO driver has been improved to handle the
"DSP GPIO" found on the TI Keystone 2 SoC:s.
- ADNP driver switched to use gpiolib irqchip helpers.
- Refactor the DWAPB driver to support being instantiated
from and MFD cell (platform device).
- Incremental feature improvement in the Zynq, MCP23S08,
DWAPB, OMAP, Xilinx and Crystalcove drivers.
- Various minor fixes.
