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.

acpi_dev_present() was originally named after pci_dev_present()
to signify the similarity of the two functions.
However Rafael J. Wysocki pointed out that the exported function
acpi_dev_present() is easily confused with the non-exported
acpi_device_is_present(). Additionally in ACPI parlance the term
"present" usually refers to the "device is present" bit returned
by the _STA control method, yet acpi_dev_present() merely checks
presence in the namespace. It does not invoke _STA at all, let
alone check the "device is present" bit.
As suggested by Rafael, rename the function to acpi_dev_found()
and adjust all existing call sites.

If the system enters S3 during a playback, codec power needs to
be turned OFF during suspend and restored during resume. With
this patch the AFG node is set to D3 and codec power is turned
OFF during controller suspend call.
During resume, the codec power is left in ON state if the
playback was in progress while suspending.
Also setting power state for AFG node is optimized. With this the
loop with timeout is removed and codec_read is used instead.

Jack plug status is rechecked at resume to handle plug/unplug
in S3 when the chip has no power.
Suspend/resume callbacks are moved from the i2c dev_pm_ops to
snd_soc_codec_driver. soc_resume_deferred is a delayed work
which may trigger nau8825_set_bias_level. The bias change races
against dev_pm_ops, causing jack detection issues.
soc_resume_deferred ensures bias change and snd_soc_codec_driver
suspend/resume are sequenced correctly.

In PRE PMD of widget handler DSP resources are allocated after
the creation of DSP pipe and modules and in POST PMD DSP
resources are destroyed.
If there is any failure in pipe or module creation in PRE PMD,
pcm trigger fails and finally POST PMD gets called and DSP
resources are freed, without getting allocated.
Fixes the DSP resource de-allocation by allocating the resource
before creation of pipe and module in PRE PMD and in POST PMD,
free the resources.

- An extension of sequencer API for advertising the card / pid
- Small fixes in compress-offload and jack layers
HD-audio:
- Dynamic PCM assignment in HDMI/DP codec; preparation for upcoming
DP-MST support
- Lots of code refactoring for sharing with ASoC SKL driver
- Regression fixes for Intel HDMI/DP
- Fixups for CX20724 codec, Lenovo AiO
USB-audio:
- Add quirk_alias option to make quirk debugging easier
- Fixes for possible Oops by malformed firmware
Firewire:
- Add support for FW-1804 in tascam driver
- Improvements / changes in card registration, multi stream handling,

- Lots of code refactoring
ASoC:
- Enhancements of still ongoing topology API
- Lots of commits for Intel Skylake support including HDMI support
- A few Intel Atom driver updates for recent devices
- Lots of improvements to the Renesas drivers
- Capture support for Qualcomm drivers
- Support for TI DaVinci DRA7xxx devices

The dummy component is reused for all cards so we special case and don't
bind it to any of them. This means that code like that displaying the
component widgets that tries to look at the card will crash. In the
future we will fix this by ensuring that the dummy component looks like
other components but that is invasive and so not suitable for a fix.
Instead add a special case check here.

Pull regulator updates from Mark Brown:
"This has been an extremely quiet release for the regulator API, aside
from bugfixes and small enhancements the only thing that really stands
out are the new drivers for Action Semiconductors ACT8945A, HiSilicon
HI665x, and the Maxim MAX20024 and MAX77620"

gcc warns about the possibilty of accessing a property read from
devicetree in cs35l32_i2c_probe() when it has not been initialized
because CONFIG_OF is disabled:
sound/soc/codecs/cs35l32.c: In function 'cs35l32_i2c_probe':
sound/soc/codecs/cs35l32.c:278:2: warning: 'val' may be used uninitialized in this function [-Wmaybe-uninitialized]
The code is actually correct because it checks the dev->of_node
variable first and we know this is NULL here when CONFIG_OF
is disabled, but Russell King noticed that it's broken when
we probe the device using DT, and the properties are absent.
The code already has some checking for incorrect values, and
I keep that checking unchanged here, but add an additional
check for an error returned by the property accessor functions
that now gets handled the same way as incorrect data in the
properties.

Pull dma_*_writecombine rename from Ingo Molnar:
"Rename dma_*_writecombine() to dma_*_wc()
This is a tree-wide API rename, to move the dma_*() write-combining
APIs closer in name to their usual API families. (The old API names
are kept as compatibility wrappers to not introduce extra breakage.)
The patch was Coccinelle generated"

dma, mm/pat: Rename dma_*_writecombine() to dma_*_wc()
The main thing in terms of the core this time around has been some
additional framework work for dynamic topologies (though we *still*
don't appear to have a stable ABI for the topology code, it's probably
worth considering if this will ever happen...). Otherwise the work has
almost all been in the drivers:
- HDMI support for Sky Lake, along with other fixes and enhancements
for the Intel drivers.
- Lots of improvements to the Renesas drivers.
- Capture support for Qualcomm drivers.
- Support for TI DaVinci DRA7xxx devices.
- New machine drivers for Freescale systems with Cirrus CODECs,
Mediatek systems with RT5650 CODECs.
- New CPU drivers for Allwinner S/PDIF controllers
- New CODEC drivers for Maxim MAX9867 and MAX98926 and Realtek RT5514.
