Pull ARM updates from Russell King:
"Another mixture of changes this time around:- Split XIP linker file from main linker file to make it more
maintainable, and various XIP fixes, and clean up a resulting
macro.- Decompressor cleanups from Masahiro Yamada
- Avoid printing an error for a missing L2 cache
- Remove some duplicated symbols in System.map, and move
vectors/stubs back into kernel VMA- Various low priority fixes from Arnd
- Updates to allow bus match functions to return negative errno
values, touching some drivers and the driver core. Greg has acked
these changes.- Virtualisation platform udpates form Jean-Philippe Brucker.
- Security enhancements from Kees Cook
- Rework some Kconfig dependencies and move PSCI idle management code
out of arch/arm into drivers/firmware/psci.c- ARM DMA mapping updates, touching media, acked by Mauro.
- Fix places in ARM code which should be using virt_to_idmap() so
that Keystone2 can work.- Fix Marvell Tauros2 to work again with non-DT boots.
- Provide a delay timer for ARM Orion platforms"

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for kernel v4.6. There is quite a
lot of interesting stuff going on.The patches to other subsystems and arch-wide are ACKed as far as
possible, though I consider things like per-arch as
essentially a part of the GPIO subsystem so it should not be needed.Core changes:
- The gpio_chip is now a *real device*. Until now the gpio chips
were just piggybacking the parent device or (gasp) floating in
space outside of the device model.We now finally make GPIO chips devices. The gpio_chip will create
a gpio_device which contains a struct device, and this gpio_device
struct is kept private. Anything that needs to be kept private
from the rest of the kernel will gradually be moved over to the
gpio_device.- As a result of making the gpio_device a real device, we have added
resource management, so devm_gpiochip_add_data() will cut down on
overhead and reduce code lines. A huge slew of patches convert
almost all drivers in the subsystem to use this.- Building on making the GPIO a real device, we add the first step of
a new userspace ABI: the GPIO character device. We take small
steps here, so we first add a pure *information* ABI and the tool
"lsgpio" that will list all GPIO devices on the system and all
lines on these devices.We can now discover GPIOs properly from userspace. We still have
not come up with a way to actually *use* GPIOs from userspace.- To encourage people to use the character device for the future, we
have it always-enabled when using GPIO. The old sysfs ABI is still
opt-in (and can be used in parallel), but is marked as deprecated.We will keep it around for the foreseeable future, but it will not
be extended to cover ever more use cases.Cleanup:
- Bjorn Helgaas removed a whole slew of per-architecture
includes.This dates back to when GPIO was an opt-in feature and no shared
library even existed: just a header file with proper prototypes was
provided and all semantics were up to the arch to implement. These
patches make the GPIO chip even more a proper device and cleans out
leftovers of the old in-kernel API here and there.Still some cruft is left but it's very little now.
- There is still some clamping of return values for .get() going on,
but we now return sane values in the vast majority of drivers and
the errorpath is sanitized. Some patches for powerpc, blackfin and
unicore still drop in.- We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
implementations to use gpiochip_add_data() and cut down on code
lines.- MPC8xxx is converted to use the generic GPIO helpers.
- ATH79 is converted to use the generic GPIO helpers.
New drivers:
- WinSystems WS16C48
- Acces 104-DIO-48E
- F81866 (a F7188x variant)
- Qoric (a MPC8xxx variant)
- TS-4800
- SPI serializers (pisosr): simple 74xx shift registers connected to
SPI to obtain a dirt-cheap output-only GPIO expander.- Texas Instruments TPIC2810
- Texas Instruments TPS65218
- Texas Instruments TPS65912
- X-Gene (ARM64) standby GPIO controller"

Introduce gpiod_get_optional() and gpiod_get_index_optional() helpers
that make it easier for drivers to handle optional GPIOs.Currently in order to handle optional GPIOs, a driver needs to special
case error handling for -ENOENT, such as this:gpio = gpiod_get(dev, "foo");
if (IS_ERR(gpio)) {
if (PTR_ERR(gpio) != -ENOENT)
return PTR_ERR(gpio);gpio = NULL;
}if (gpio) {
/* set up GPIO */
}With these new helpers the above is reduced to:
gpio = gpiod_get_optional(dev, "foo");
if (IS_ERR(gpio))
return PTR_ERR(gpio);if (gpio) {
/* set up GPIO */
}While at it, device-managed variants of these functions are also
provided.Signed-off-by: Thierry Reding

Pull staging driver tree changes from Greg KH:
"Here's the big drivers/staging/ update for 3.14-rc1Lots and lots of cleanups, IIO driver updates are also mixed in here
due to the subsystem still crossing staging and drivers/iio/, and the
dwc2 driver is moved out of staging. There's a new driver (rts5208),
which ends up making us adding more lines than removing, but overall
there was lots of work toward moving code out of here, which was goodAll of this has been in linux-next with no reported issues"

…/iio into staging-next
Jonathan writes:
First set of new features, drivers and cleanups for IIO in the 3.14 cycle.
This mostly consists of patches that didn't quite make the last cycle. Lots
of interesting things under review currently.Core:
- Add devm_iio_device_register/unregister. I took some convincing on whether
there would be many devices that really were simple enough to need no
explicit actions on removal. Turns out there are some.
- Move some stray docs to above the relevant implemenation.
- Drop a redundant repeated check on the fact the trigger has actually changed
when there is a userspace attempt change it.Drivers:
New drivers
- Freescale MPL3115A2 Pressure / temperature sensorNew functionality
- hid_sensors: add sensitivity support.DT bindings
- tsl2563
- hmc5843Cleanups
- Drop unused scan_type from viperboard adc driver.
- devm_iio_device_register used in viperboard, ad5421, ad5755, adis16130,
adxrs450, vcnl4000, adis16220, ad7816, lpc32xx, adt7316, adis16060, isl29018
and ad2s1200. Note that this was proposed in a number of other drivers
and this revealed a number of missorderings in remove functions. Also for
now I have blocked this on any device that any hardware suspend suport on
the basis that we probably want to power down devices if they have no driver
support loaded.

Pull spi updates from Mark Brown:
"As well as the usual driver updates and cleanups there's a few
improvements to the core here:- The start of some improvements to factor out more of the SPI
message loop into the core. Right now this is just simplifying the
code a bit but hopefully next time around we'll also have managed
to roll out some noticable performance improvements which drivers
can take advantage of.
