This is the bulk of the GPIO changes for the v4.14 cycle:

Core changes
- Allow the GPIO irqchip to allocate IRQs dynamically. This is
  an important change on systems where only a restricted number
  of IRQs, lesser than the number of GPIO lines, can be utilized.
  Now we can allocate these on a first-come-first-served basis
  instead of hogging up valuable IRQ lines.
- Serious fix-up of the kerneldoc documentation and inclusion
  into the kerneldoc builds.
- Pulled in the IRQ simulator from the IRQ core tree and use
  this in the GPIO mockup driver for exhaustive testing of
  interrupt abilities.

New drivers
- New driver for ThunderX and OCTEON-TX. This is especially
  interesting as it picks up improvements from the IRQ core that
  allow us to handle fasteoi ACKs upwards in a hierarchy when
  there are IRQ flag latches on several levels in a hierarchy.
  Very interesting work here.
- New subdriver for Renesas R-Car r8a7745 (RZ/G1E).

Misc
- Several fixes and improvements for Xilinx Zynq GPIO.
- Support an enablement GPIO for the 74x164 GPIO.
- Switch a bunch of chips to use devres to allocate irq
  descriptors.
- A bunch of constification fixes.

Device properties framework updates for v4.14-rc1

 - Introduce fwnode operations for all of the separate types of
   "firmware nodes" that can be handled by the device properties
   framework and drop the type field from struct fwnode_handle
   (Sakari Ailus, Arnd Bergmann).

 - Make the device properties framework use const fwnode arguments
   where possible (Sakari Ailus).

 - Add a helper for the consolidated handling of node references
   to the device properties framework (Sakari Ailus).

 - Switch over the ACPI part of the device properties framework
   to the new UUID API (Andy Shevchenko).

ACPI updates for v4.14-rc1

   including:
   * Alias operator handling update (Bob Moore).
   * Deferred resolution of reference package elements (Bob Moore).
   * Support for the _DMA method in walk resources (Bob Moore).

   devices connected at boot time where we miss an early hotplug
   event due to a delay in GPE enabling (Rafael Wysocki).

 - Rework the handling of PCI bridges when setting up ACPI-based
   device wakeup in order to avoid disabling wakeup for bridges

   the BERT error region over sysfs and update APEI MAINTAINERS
   entry with reviewers information (Borislav Petkov, Dongjiu Geng,

 - Fix a potential initialization ordering issue in the ACPI EC
   driver and clean it up somewhat (Lv Zheng).

   workaround in it to a new platform (m400) and to work around
   an Xgene UART clock issue (Graeme Gregory).

 - Add a new utility function to the ACPI core to support using
   ACPI OEM ID / OEM Table ID / Revision for system identification
   in blacklisting or similar and switch over the existing code
   already using this information to this new interface (Toshi Kani).

 - Fix an xpower PMIC issue related to GPADC reads that always return
   0 without extra pin manipulations (Hans de Goede).

   method (based on the CPU load) for all types of systems in the
   active mode (Rafael Wysocki, Srinivas Pandruvada).

 - Rework the cpufreq core and governors to make it possible to
   take cross-CPU utilization updates into account and modify the
   schedutil governor to actually do so (Viresh Kumar).

 - Clean up the handling of transition latency information in the
   cpufreq core and untangle it from the information on which drivers
   cannot do dynamic frequency switching (Viresh Kumar).

 - Add support for new SoCs (MT2701/MT7623 and MT7622) to the
   mediatek cpufreq driver and update its DT bindings (Sean Wang).

 - Modify the cpufreq dt-platdev driver to autimatically create
   cpufreq devices for the new (v2) Operating Performance Points
   (OPP) DT bindings and update its whitelist of supported systems
   (Viresh Kumar, Shubhrajyoti Datta, Marc Gonzalez, Khiem Nguyen,
   Finley Xiao).

   constraints checks to the ACPI suspend-to-idle code (Rafael
   Wysocki, Srinivas Pandruvada).

 - Prefer suspend-to-idle over S3 on ACPI-based systems with the
   ACPI_FADT_LOW_POWER_S0 flag set and the Low Power Idle S0 _DSM
   interface present in the ACPI tables (Rafael Wysocki).

 - Update documentation related to system sleep and rename a number
   of items in the code to make it cleare that they are related to
   suspend-to-idle (Rafael Wysocki).

 - Export a variable allowing device drivers to check the target
   system sleep state from the core system suspend code (Florian
   Fainelli).

 - Clean up the cpuidle subsystem to handle the polling state on

   Buffers.

ASoC: Fixes for the CS43130 driver

A couple of warning fixes for the newly added CS43130 driver.

ASoC: Updates for v4.14

This is quite a large release by volume of patches and diff, a lot of
that is mechanical cleanup patches but it's great to also see a range of
vendors actively working on adding new features and fixing issues in
their drivers.  Intel and Realtek have been especially active here.

 - Continued work towards moving everything to the component model from
   Morimoto-san.
 - Use of devres for jack detection GPIOs, eliminating some potential
   resource leaks.
 - Jack detection support for Qualcomm MSM8916.

headset detection breakage, and a regression in simple-card parser
code.
