Hi Linus,
here is the bulk of GPIO changes for the v4.7 development
cycle.
There are a few patches to other subsystems and arches here,
all should be ACKed by respective maintainer I think. The MIPS
patch created a trivial merge conflict in linux-next so you may
see it when pulling this or the MIPS tree. Piece of cake.
There is also a patch to irqdomain (exporting a single function)
which got ACKed by tglx and Marc.
A lot of patches are written by myself, I guess I'm maintaining
properly for once. Or being bad at pushing work to others, I don't
know which one it is.
The rest of the details are in the signed tag.
Please pull it in!
Yours,
Linus Walleij

MIPS: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB (2016-05-11
13:52:05 +0200)
----------------------------------------------------------------
This is the bulk of GPIO changes for kernel cycle v4.7:
Core infrastructural changes:
- Support for natively single-ended GPIO driver stages. This
means that if the hardware has registers to configure open
drain or open source configuration, we use that rather than
(as we did before) try to emulate it by switching the line
to an input to get high impedance. This is also documented
throughly in Documentation/gpio/driver.txt for those of you
who did not understand one word of what I just wrote.
- Start to do away with the unnecessarily complex and
unitelligible ARCH_REQUIRE_GPIOLIB and
ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from
the time when the GPIO subsystem was unmaintained. Archs can
now just select GPIOLIB and be done with it, cleanups to
arches will trickle in for the next kernel. Some minor archs
ACKed the changes immediately so these are included in this
pull request.
- Advancing the use of the data pointer inside the GPIO device
for storing driver data by switching the PowerPC, Super-H
Unicore and a few other subarches or subsystem drivers in
ALSA SoC, Input, serial, SSB, staging etc to use it.
- The initialization now reads the input/output state of the
GPIO lines, so that each GPIO descriptor knows - if this
callback is implemented - whether the line is input or
output. This also reflects nicely in userspace "lsgpio".
- It is now possible to name GPIO producer names, line names,
from the device tree. (Platform data has been supported for
a while.) I bet we will get a similar mechanism for ACPI
one of those days. This makes is possible to get sensible
producer names for e.g. GPIO rails in "lsgpio" in userspace.
New drivers:
- New driver for the Loongson1.
- The XLP driver now supports Broadcom Vulcan ARM64.
- The IT87 driver now supports IT8620 and IT8628.
- The PCA953X driver now supports Galileo Gen2.
Driver improvements:
- MCP23S08 was switched to use the gpiolib irqchip helpers and
now also suppors level-triggered interrupts.
- 74x164 and RCAR now supports the .set_multiple() callback
- AMDPT was converted to use generic GPIO.
- TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
support the new single ended callback for open drain
and in some cases open source.
- Implement the .get_direction() callback for a few more drivers
like PL061, Xgene.
Cleanups:
- Paul Gortmaker combed through the drivers and de-modularized
those who are not really modules.
- Move the GPIO poweroff DT bindings to the power subdir where
they belong.
- Rename gpio-generic.c to gpio-mmio.c, which is much more to the
point. That's what it is handling, nothing more, nothing less.
