This is the bulk of GPIO changes for the v4.17 kernel cycle:

New drivers:

- Nintendo Wii GameCube GPIO, known as "Hollywood"

- Raspberry Pi mailbox service GPIO expander

- Spreadtrum main SC9860 SoC and IEC GPIO controllers.

Improvements:

- Implemented .get_multiple() callback for most of the
  high-performance industrial GPIO cards for the ISA bus.

- ISA GPIO drivers now select the ISA_BUS_API instead of
  depending on it. This is merged with the same pattern
  for all the ISA drivers and some other Kconfig cleanups
  related to this.

Cleanup:

- Delete the TZ1090 GPIO drivers following the deletion of
  this SoC from the ARM tree.

- Move the documentation over to driver-api to conform with
  the rest of the kernel documentation build.

- Continue to make the GPIO drivers include only
  <linux/gpio/driver.h> and not the too broad <linux/gpio.h>
  that we want to get rid of.

- Managed to remove VLA allocation from two drivers pending
  more fixes in this area for the next merge window.

- Misc janitorial fixes.

media updates for v4.17-rc1

regulator: Updates for v4.17

A very small set of updates for the regulator API this time around,
there's a few bug fixes and also:

 - Conversion of the regulator API to use GPIO descriptors rather than
   numbers from Linus Walleij.
 - New drivers for Marvell 88PG86x and Qualcomm PM8998 and PMI8998.

ASoC: Updates for v4.17

This is a *very* big release for ASoC.  Not much change in the core but
there s the transition of all the individual drivers over to components
which is intended to support further core work.  The goal is to make it
easier to do further core work by removing the need to special case all
the different driver classes in the core, many of the devices end up
being used in multiple roles in modern systems.

We also have quite a lot of new drivers added this month of all kinds,
quite a few for simple devices but also some more advanced ones with
more substantial code.

 - The biggest thing is the huge series from Morimoto-san which
   converted everything over to components.  This is a huge change by
   code volume but was fairly mechanical
 - Many fixes for some of the Realtek based Baytrail systems covering
   both the CODECs and the CPUs, contributed by Hans de Goode.
 - Lots of cleanups for Samsung based Odroid systems from Sylwester
   Nawrocki.
 - The Freescale SSI driver also got a lot of cleanups from Nicolin
   Chen.
 - The Blackfin drivers have been removed as part of the removal of the
   architecture.
 - New drivers for AKM AK4458 and AK5558, several AMD based machines,
   several Intel based machines, Maxim MAX9759, Motorola CPCAP,
   Socionext Uniphier SoCs, and TI PCM1789 and TDA7419
