The driver currently registers a pair of irq handlers using

Unfortunately, this breaks PREEMPT_RT builds, where a spinlock can sleep,
and is thus not able to be acquired from a hardirq handler. This patch gets
rid of the threaded handler and pushes all interrupt handling into the
hardirq context, and uses request_irq().

As we had a lot of tools and docs work in this set, I have broken those
out into their own categories in this description.
Fixes from the pull request '4th set of IIO fixes for the 4.2 cycle'.
* Poll functions for both event chardev and the buffer one were returning
negative error codes (via a positive value).
* A recent change to lsiio adding some error handling that was wrong and
stopped the tool working.
* bmg160 was missing some dependencies in Kconfig
* berlin2-adc had a misshandled register (wrote a value rather than a bitmap)
New device support
* TI opt3001 light sensor
* TXC PA12 ALS and proximity sensor.
* mcp3301 ADC support (in mcp320x driver)
* ST lsm303agr accelerometer and magnetometer drivers (plus some st-sensors
common support to allow different WHOAMI register addresses, devices with
fixed scale and allow interrupt equiped magnetometers).
* ADIS16305, ADIS16367, ADIS16445IMUs (in the adis16400 driver)
* ADIS16266 gyro (in the adis16260 driver)
* ADIS16137 gyro (in the adis16136 driver)
New functionality

* Inverse unit conversion macros to aid handing of values written to sysfs
attributes.
Core cleanup
* Forward declaration of struct iio_trigger to avoid a compile warning.
Driver cleanup / fixes
* mxs-lradc
- Clarify which parts are supported.
- Fix spelling erorrs.
- Missing/extra includes
- reorder includes
- add datasheet name listings for all usable channels (to allow them
to be bound by name from consumer drivers)
* acpi-als - add some function prefixes as per general iio style.
* bmc150_magn - replace a magic value with the existing define.
* vf610 - determine possible sample frequencies taking into account the
electrical characteristics (defining a minimum sample time)
* dht11
- whitespace
- additional docs
- avoid mulitple assignments in one line
- Use the new funciton ktime_get_resolution_ns to cleanup a nasty trick
previously used for timing.
* Fix all drivers that consider 0 a valid IRQ for historical reasons.
* Export I2C module alias info where previously missing (to allow autoprobing)
* Export OF module alias info where previously missing.
* mmc35240 - switch some variables into arrays to improve readability.
* mlx90614 - define some magic numbers for readability.
* bmc150_magn
- expand area locked by a mutex to cover all the use of the
data->buffer.

* adis16300 - has an undocumented product id and serial number registers so
use them.
* iio_simple_dummy - fix some wrong code indentation.

- Kernel ptes are marked with a global bit which allows the kernel to

both entries of an adjacent even/odd pte pair need to have the
global bit set. There has been a subtle race in setting the other

pathological workloads that essentially do mostly vmalloc/vfree to
trigger this.
This pull request fixes the 64-bit case but leaves the case of 32
bit CPUs with 64 bit ptes unsolved for now. The unfixed cases
affect hardware that is not available in the field yet.
- Instruction emulation requires loading instructions from user space
but the current fast but simplistic approach will fail on pages
that are PROT_EXEC but !PROT_READ. For this reason we temporarily
do not permit this permission and will map pages with PROT_EXEC |

Add inverse unit conversion macro to convert from standard IIO units to
units that might be used by some devices.
Those are useful in combination with scale factors that are specified as
IIO_VAL_FRACTIONAL. Typically the denominator for those specifications will
contain the maximum raw value the sensor will generate and the numerator
the value it maps to in a specific unit. Sometimes datasheets specify those
in different units than the standard IIO units (e.g. degree/s instead of
rad/s) and so we need to do a unit conversion.
From a mathematical point of view it does not make a difference whether we
apply the unit conversion to the numerator or the inverse unit conversion
to the denominator since (x / y) / z = x / (y * z). But as the denominator
is typically a larger value and we are rounding both the numerator and
denominator to integer values using the later method gives us a better
precision (E.g. the relative error is smaller if we round 8000.3 to 8000
rather than rounding 8.3 to 8).
This is where in inverse unit conversion macros will be used.

Pull sound fixes from Takashi Iwai:
"The only bulk changes in this request is ABI updates for ASoC topology
API. It's a new API that was introduced in 4.2, and we'd like to
avoid ABI change after the release, so it's taken now. As there is no
real in-tree user for this API, it should be fairly safe.
Other than that, the usual small fixes are found in various drivers:
ASoC cs4265, rt5645, intel-sst, firewire, oxygen and HD-audio"
