CORE:
- Fix the semantics of raw GPIO to actually be raw. No
inversion semantics as before, but also no open draining,
and allow the raw operations to affect lines used for
interrupts as the caller supposedly knows what they are
doing if they are getting the big hammer.
- Rewrote the __inner_function() notation calls to names that
make more sense. I just find this kind of code disturbing.
- Drop the .irq_base() field from the gpiochip since now all
IRQs are mapped dynamically. This is nice.
- Support for .get_multiple() in the core driver API. This
allows us to read several GPIO lines with a single
register read. This has high value for some usecases: it
can be used to create oscilloscopes and signal analyzers
and other things that rely on reading several lines at
exactly the same instant. Also a generally nice
optimization. This uses the new assign_bit() macro from
the bitops lib that was ACKed by Andrew Morton and
is implemented for two drivers, one of them being the
generic MMIO driver so everyone using that will be able
to benefit from this.
- Do not allow requests of Open Drain and Open Source
setting of a GPIO line simultaneously. If the hardware
actually supports enabling both at the same time the
electrical result would be disastrous.
- A new interrupt chip core helper. This will be helpful
to deal with "banked" GPIOs, which means GPIO controllers
with several logical blocks of GPIO inside them. This
is several gpiochips per device in the device model, in
contrast to the case when there is a 1-to-1 relationship
between a device and a gpiochip.
NEW DRIVERS:
- Maxim MAX3191x industrial serializer, a very interesting
piece of professional I/O hardware.
- Uniphier GPIO driver. This is the GPIO block from the
recent Socionext (ex Fujitsu and Panasonic) platform.
- Tegra 186 driver. This is based on the new banked GPIO
infrastructure.
OTHER IMPROVEMENTS:
- Some documentation improvements.
- Wakeup support for the DesignWare DWAPB GPIO controller.
- Reset line support on the DesignWare DWAPB GPIO controller.
- Several non-critical bug fixes and improvements for the
Broadcom BRCMSTB driver.
- Misc non-critical bug fixes like exotic errorpaths, removal
of dead code etc.
- Explicit comments on fall-through switch() statements.

Here is the "big" staging and IIO driver update for 4.15-rc1.
Lots and lots of little changes, almost all minor code cleanups as the
Outreachy application process happened during this development cycle.
Also happened was a lot of IIO driver activity, and the typec USB code
moving out of staging to drivers/usb (same commits are in the USB tree
on a persistent branch to not cause merge issues.)
Overall, it's a wash, I think we added a few hundred more lines than
removed, but really only a few thousand were modified at all.
All of these have been in linux-next for a while. There might be a
merge issue with Al's vfs tree in the pi433 driver (take his changes,
they are always better), and the media tree with some of the odd atomisp
cleanups (take the media tree's version).

Pull timer updates from Thomas Gleixner:
"Yet another big pile of changes:
- More year 2038 work from Arnd slowly reaching the point where we
need to think about the syscalls themself.
- A new timer function which allows to conditionally (re)arm a timer
only when it's either not running or the new expiry time is sooner
than the armed expiry time. This allows to use a single timer for
multiple timeout requirements w/o caring about the first expiry
time at the call site.
- A new NMI safe accessor to clock real time for the printk timestamp
work. Can be used by tracing, perf as well if required.
- A large number of timer setup conversions from Kees which got
collected here because either maintainers requested so or they
simply got ignored. As Kees pointed out already there are a few
trivial merge conflicts and some redundant commits which was
unavoidable due to the size of this conversion effort.
- Avoid a redundant iteration in the timer wheel softirq processing.
- Provide a mechanism to treat RTC implementations depending on their
hardware properties, i.e. don't inflict the write at the 0.5
seconds boundary which originates from the PC CMOS RTC to all RTCs.
No functional change as drivers need to be updated separately.
- The usual small updates to core code clocksource drivers. Nothing
really exciting"

Pull irq core updates from Thomas Gleixner:
"A rather large update for the interrupt core code and the irq chip drivers:
- Add a new bitmap matrix allocator and supporting changes, which is
used to replace the x86 vector allocator which comes with separate
pull request. This allows to replace the convoluted nested loop
allocation function in x86 with a facility which supports the
recently added property of managed interrupts proper and allows to
switch to a best effort vector reservation scheme, which addresses
problems with vector exhaustion.
- A large update to the ARM GIC-V3-ITS driver adding support for
range selectors.
- New interrupt controllers:
- Meson and Meson8 GPIO
- BCM7271 L2
- Socionext EXIU
If you expected that this will stop at some point, I have to
disappoint you. There are new ones posted already. Sigh!
- STM32 interrupt controller support for new platforms.
- A pile of fixes, cleanups and updates to the MIPS GIC driver
- The usual small fixes, cleanups and updates all over the place.
Most visible one is to move the irq chip drivers Kconfig switches
into a separate Kconfig menu"

Small Things:
- Move OpenRISC docs into Documentation and clean them up
- Document previously undocumented devicetree bindings
- Update the or1ksim dts to use stdout-path
OpenRISC SMP support details:
- First the "use shadow registers" and "define CPU_BIG_ENDIAN as true"
get the architecture ready for SMP.
- The "add 1 and 2 byte cmpxchg support" and "use qspinlocks and
qrwlocks" add the SMP locking infrastructure as needed. Using the
qspinlocks and qrwlocks as suggested by Peter Z while reviewing the
original spinlocks implementation.
- The "support for ompic" adds a new irqchip device which is used for
IPI communication to support SMP.
- The "initial SMP support" adds smp.c and makes changes to all of the
necessary data-structures to be per-cpu.
- The remaining patches are bug fixes and debug helpers which I wanted
to keep separate from the "initial SMP support" in order to allow them
to be reviewed on their own. This includes:
- add cacheflush support to fix icache aliasing
- fix initial preempt state for secondary cpu tasks

Pull OpenRISC updates from Stafford Horne:
"The OpenRISC work is a bit more interesting this time, adding SMP
support and a few general cleanups.
Small Things:
- Move OpenRISC docs into Documentation and clean them up
- Document previously undocumented devicetree bindings
- Update the or1ksim dts to use stdout-path
OpenRISC SMP support details:
- First the "use shadow registers" and "define CPU_BIG_ENDIAN as
true" get the architecture ready for SMP.
- The "add 1 and 2 byte cmpxchg support" and "use qspinlocks and
qrwlocks" add the SMP locking infrastructure as needed. Using the
qspinlocks and qrwlocks as suggested by Peter Z while reviewing the
original spinlocks implementation.
- The "support for ompic" adds a new irqchip device which is used for
IPI communication to support SMP.
- The "initial SMP support" adds smp.c and makes changes to all of
the necessary data-structures to be per-cpu.
The remaining patches are bug fixes and debug helpers which I wanted
to keep separate from the "initial SMP support" in order to allow them
to be reviewed on their own. This includes:
- add cacheflush support to fix icache aliasing
- fix initial preempt state for secondary cpu tasks
- sleep instead of spin on secondary wait
- support framepointers and STACKTRACE_SUPPORT
- enable LOCKDEP_SUPPORT and irqflags tracing
- timer sync: Add tick timer sync logic
- fix possible deadlock in timer sync, pointed out by mips guys

Merge 4.14-rc3 in order to pick up the new timer_setup function.
IPI driver for the Open Multi-Processor Interrupt Controller (ompic) as
described in the Multi-core support section of the OpenRISC 1.2
architecture specification:
https://github.com/openrisc/doc/raw/master/openrisc-arch-1.2-rev0.pdf
Each OpenRISC core contains a full interrupt controller which is used in
the SMP architecture for interrupt balancing. This IPI device, the
ompic, is the only external device required for enabling SMP on
OpenRISC.
Pending ops are stored in a memory bit mask which can allow multiple
pending operations to be set and serviced at a time. This is mostly
borrowed from the alpha IPI implementation.

Since hub usb2517 is going to be supported by the usb251xb driver,
the bindings need to be properly updated. Particularly:
- add "microchip,usb2517" and "microchip,usb2517i" compatible strings.
- add "boolean" description to all the properties, which really accept
a boolean value including a new one "led-{usb,speed}-mode".
- move reset-gpios property to the optional section. It isn't
defined as required in the code and shouldn't be required at all, since
hardware may handle reset pins by itself.
- add new led-{usb,speed}-mode mode property. USB2517 device supports
two LED modes: USB mode and speed (default) indication mode. The last one
can be switched on by this property.
- add {bp,sp}-max-{total,removable}-current-microamp property measured in
microamp. It hasn't been defined as property before. Since the limitation
specified by these parameters is hardware specific it needs to be defined
in dts.

Add fallback compatibility strings for R-Car Gen 1, 2 and 3.
In the case of Renesas R-Car hardware we know that there are generations of
SoCs, f.e. Gen 1 and 2. But beyond that its not clear what the relationship
between IP blocks might be. For example, I believe that r8a7790 is older
than r8a7791 but that doesn't imply that the latter is a descendant of the
former or vice versa.
We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.
For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme is being adopted for
drivers for Renesas SoCs.

This documents the devicetree bindings for the SDIO/MMC host found in
Amlogic Meson8 and Meson8b SoCs. It supports the SD specification v2.0
and the eMMC specification v4.41.
It has an internal "mux" which allows connecting up to three MMC devices
to it. The maximum supported bus-width is 4-bits.
Amlogic's GPL kernel sources call it "SDIO" to differentiate it from the
other MMC controller in (at least the Meson8 and Meson8b) the SoCs (they
call the other one "SDHC", which supports a bus-width of up to 8-bits).

Improve the binding example by removing the leading 0 from '@08' notation,
which fixes the following build warnings:
Warning (unit_address_format): Node /pfuze100@08 unit name should not have leading 0s
Warning (unit_address_format): Node /pfuze200@08 unit name should not have leading 0s
Warning (unit_address_format): Node /pfuze3000@08 unit name should not have leading 0s
