gpio-v4.7-1

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.

pm-4.7-rc1

   them to get rid of some platform-specific boilerplate code if they

   driver (Srinivas Pandruvada).

   Bhat).

   Javier Martinez Canillas, Paul Gortmaker, Sudeep Holla).

 - Assorted cpufreq fixes and cleanups (Joe Perches, Arnd Bergmann).

 - Fixes and cleanups in the OPP (Operating Performance Points)
   framework, mostly related to OPP sharing, and reorganization of
   OF-dependent code in it (Viresh Kumar, Arnd Bergmann, Sudeep Holla).

 - New "passive" governor for devfreq (for SoC subsystems that will
   rely on someone else for the management of their power resources)
   and consolidation of devfreq support for Exynos platforms, coding
   style and typo fixes for devfreq (Chanwoo Choi, MyungJoo Ham).

 - PM core fixes and cleanups, mostly to make it work better with the
   generic power domains (genpd) framework, and updates for that
   framework (Ulf Hansson, Thierry Reding, Colin Ian King).

 - Intel Broxton support for the intel_idle driver (Len Brown).

 - cpuidle core optimization and fix (Daniel Lezcano, Dave Gerlach).

 - ARM cpuidle cleanups (Jisheng Zhang).

   Mattia Dongili, Thomas Renninger).

pm+acpi-4.6-rc7

Power management and ACPI fixes for v4.6-rc7

 - Fix for a recent regression in the intel_pstate driver causing
   it to fail to restore the HWP (HW-managed P-states) configuration
   of the boot CPU after suspend-to-RAM (Rafael Wysocki).

 - Fix for two recent regressions in the intel_pstate driver, one
   that can trigger a divide by zero if the driver is accessed via
   sysfs before it manages to take the first sample and one causing
   it to fail to update a structure field used in a trace point, so
   the information coming from it is less useful (Rafael Wysocki).

 - Fix for a problem in the sti-cpufreq driver introduced during
   the 4.5 cycle that causes it to break CPU PM in multi-platform
   kernels by registering cpufreq-dt (which subsequently doesn't
   work) unconditionally and preventing the driver that would
   actually work from registering (Sudeep Holla).

 - Stable-candidate fix for an ARM64 cpuidle issue causing idle
   state usage counters to be incorrectly updated for idle states
   that were not entered due to errors (James Morse).

 - Fix for a recently introduced issue in the OPP (Operating
   Performance Points) framework causing it to print bogus error
   messages for missing optional regulators (Viresh Kumar).

 - Fix for a recently introduced issue in the generic device
   properties framework that may cause it to attempt to dereferece
   and invalid pointer in some cases (Heikki Krogerus).

 - Fix for a deadlock in the ACPICA core that may be triggered
   by device (eg. Thunderbolt) hotplug (Prarit Bhargava).
