The iio sysfs ABI defines a way to specify period for roc and thresholds.
What: /sys/.../events/in_accel_x_thresh_rising_period
What: /sys/.../events/in_accel_x_thresh_falling_period
what: /sys/.../events/in_accel_x_roc_rising_period
What: /sys/.../events/in_accel_x_roc_falling_period
But there is no way to add period with the current event info enum.
Added IIO_EV_INFO_PERIOD and corresponding string.

The I2C devices that make up the STMicroelectronics MEMS sensors
may be sneakily enabled by cleverly giving the device node the same
name as a string match from the platform device ID table. However
the right method is to use the compatible string.
On detection, the ST sensors use the ID string to probe and
instatiate the right sensor driver, so pass the kernel-internal ID
string in the .data field of the OF match table, and set the I2C
client name to this name when a compatible match is used.
This avoids having misc Linux-specific strings floating around in
the device tree.

The ad7291 driver is in a reasonable shape. It does not use non-standard API/ABI
and there are no major style issues with the driver. So this patch moves it out
of staging.
There is one small warning from checkpatch which is also fixed in this patch.
The patch also sorts the #include directives in alphabetical order.

Currently the STMicroelectronics sensors only support one single
platform data item: configuration of the DRDY (data ready) pin
for a particular design. Augment the core to prioritize and take
this information from the device tree if the parent device has an
assigned device node, else fall back to passed in platform data
(usually the default data).

This particular conversion was made more complicated by the shared library
and the fact that a number of the drivers do not actually have support for
setting or reading the sampling frequency. The hardware, in those cases
investigated supports it. It's just never been implemented.

Added IIO magnetometer driver for AK09911. In functionality is resembles
AK8975 or AK8963. But there are several differences, so instead of
modifying existing AK8975 driver and keep it clean, implemented as
a separate driver.
The key differences are:
- Register map is different and have different indexes
- AK09911 is a very compact interface with no DRDY pin. So no support
of interrupt or GPIO poll
- Even for polled mode no mention on ST2 register, which is required in
ak8975 driver
- mode values are different for fuse access

A quite large set of SoC updates this cycle. In no particular order:
- Multi-cluster power management for Samsung Exynos, adding support for
big.LITTLE CPU switching on EXYNOS5
- SMP support for Marvell Armada 375 and 38x
- SMP rework on Allwinner A31
- Xilinx Zynq support for SOC_BUS, big endian
- Marvell orion5x platform cleanup, modernizing the implementation and
moving to DT.
- _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
that their platform can be enabled in the same kernel binary as most
of the other v7 platforms in the tree. \o/ The work isn't quite complete,
there's some driver fixes still needed, but the basics now work.
New SoC support added:
- Freescale i.MX6SX
- LSI Axxia AXM55xx SoCs
- Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800
- STi STIH407
Plus a large set of various smaller updates for different platforms. I'm
probably missing some important one here.

Merge tag 'soc-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc into next
Pull part one of ARM SoC updates from Olof Johansson:
"A quite large set of SoC updates this cycle. In no particular order:
- Multi-cluster power management for Samsung Exynos, adding support
for big.LITTLE CPU switching on EXYNOS5
- SMP support for Marvell Armada 375 and 38x
- SMP rework on Allwinner A31
- Xilinx Zynq support for SOC_BUS, big endian
- Marvell orion5x platform cleanup, modernizing the implementation
and moving to DT.
- _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
that their platform can be enabled in the same kernel binary as
most of the other v7 platforms in the tree. \o/
The work isn't quite complete, there's some driver fixes still
needed, but the basics now work.
New SoC support added:
- Freescale i.MX6SX
- LSI Axxia AXM55xx SoCs
- Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800
- STi STIH407
plus a large set of various smaller updates for different platforms.
I'm probably missing some important one here"

Not setting the raw parameter in the request causes it to be randomly
initialized to a value that might be different from zero or zero. This leads to
values that are randomly either raw or processed, making it very difficult to
make reliable use of the values.

(i) pressure is 20-bit unsigned, not signed; the buffer description
is incorrect; for raw reads, this is just cosmetic
(ii) temperature is 12-bit signed, not 16-bit; this affects
readout of temperatures below zero as the sign bit is incorrectly
processed

Some sensor hubs require a get feature report call to be issued soon after
changing the power state of the sensor. Without this, the sensor remains in
the current state. This patch adds a call soon after the power state.
This is retained as a generic call across all sensor hubs since the behavior
has been noticed on more than one implementation.

This (rather late) set consists only of fixes to patches earlier in the
cycle or minor fixes for other problems (such as randconfig build issues
picked up by Arnd). I've included the general minor fixes here as it is
very late in the current cycle and they can all wait for the merge window.
* Recent change to hid-sensors introduced a possible infinite loop due to a
typo. In the same series, a report interval unit read was added but in the
case where the hardware doesn't support it a value of 0 would lead to some
nasty issues. The patch sets it to the specified default of msecs.
* Anon inodes were used by IIO without being explicitly selected. This has
been true for a long time so it clearly only effects rather unusual
configurations (rand configs)
* at91 requires the input subsytem but this wasn't explicity in the Kconfig.
* A couple of parts supported by the max1363 driver were using the wrong
iio_chan_spec arrays and hence would missreport their bit depths. This has
been there a long time and was never right so isn't a regression.

For PROP_REPORT_INTERVAL, the spec does not mandate the presence
of the report interval unit in the feature report and expects the
default unit of measure to be used as milliseconds.
Currently, when the unit is not present, it gets set as zero leading
to issues in sampling frequency.
This patch sets the unit of measure to the default unit if it
is not defined by firmware.
