The iio_triggered_buffer_{predisable,postenable} functions attach/detach
the poll functions.
The iio_triggered_buffer_postenable() should be called before (to attach
the poll func) and then the
The iio_triggered_buffer_predisable() function is hooked directly without
anything, which is probably fine, as the postenable() version seems to also
do some reset/wake-up of the device.
This will mean it will be easier when removing it; i.e. it just gets
removed.

The LTC2983 is a Multi-Sensor High Accuracy Digital Temperature
Measurement System. It measures a wide variety of temperature sensors and
digitally outputs the result, in °C or °F, with 0.1°C accuracy and
0.001°C resolution. It can measure the temperature of all standard
thermocouples (type B,E,J,K,N,S,R,T), standard 2-,3-,4-wire RTDs,
thermistors and diodes.

FXOS8700CQ is a small, low-power, 3-axis linear accelerometer and 3-axis
magnetometer combined into a single package. The device features a
selectable I2C or point-to-point SPI serial interface with 14-bit
accelerometer and 16-bit magnetometer ADC resolution along with
smart-embedded functions.
FXOS8700CQ has dynamically selectable accelerationfull-scale ranges of
±2 g/±4 g/±8 g and a fixed magnetic measurement range of ±1200 μT.
Output data rates (ODR) from 1.563 Hz to 800 Hz are selectable by the user
for each sensor. Interleaved magnetic and acceleration data is available
at ODR rates of up to 400 Hz. FXOS8700CQ is available in a plastic QFN
package and it is guaranteed to operate over the extended temperature
range of –40 °C to +85 °C.

This is a new driver for the ST-Ericsson AB8500 GPADC, which
replaces the old driver in drivers/mfd/ab8500-gpadc.c and
thus gets rid of another necessarily different custom driver
from the times before IIO existed.
The AB8500 GPADC can convert 10 different channels and these
are used for monitoring voltages in the U8500 chipset, some
are used for battery charging, some for temperature
monitoring.
As this is very core functionality that a lot of drivers
depend on and was formerly compiled in with the AB8500 core
driver, we deafault it to 'y' in Kconfig: it can be compiled
out but it is really not advisible: the platform can
for example overheat if we do.

Third version with the adis rework set dropped as better to just have
a fresh version of that at some future date.
The usual mixed backs of new device support being added to drivers,
long term reworks continuing and little per driver cleanups and
features.
Also a few trivial counter subsystem tidy ups on behalf of William.
Core new feature
* Device label support. A long requested feature no one got around to
implementing before. Allows DT based provision of a 'label' that
identifies a device uniquely within a system. This differs from existing
'name' which is meant to be the part number.
New device support
* ingenic-adc
- Support for the JZ4770 SoC ADC including bindings.
* inv_mpu6050
- Add support for magnetometer in MPU925x parts.
Fiddly to do as this is actually a separate device sitting inside the
package, but with the master device being able to schedule reads etc.
Will only run if the auxiliary bus is not in use for any other devices.
Features
* ad7192
- Userspace calibration controls to do zero and full scale.
* st_lsm6dsx
- Enable latched interrupts by default for sensors events with related clear.
- Motion events and related wakeup source. This needed quite a bit of
refactoring as well.
Cleanups and minor features
* ad7192
- sysfs ABI docs
* ad7949
- Remove code to readback configuration word as driver never actually enabled
it.
- Fix incorrect xfer length. Not actually known to cause problems other
than wasted bus usage.
* adis16080
- Replace core mlock usage with local lock with more appropriate scope.
* adis16130
- Remove pointless mlock usage.
* adis16240
- Remove include of gpio.h as no gpio usage.
* atlas-ph-sensor
- Improve logical ordering of buffer predisable / postenable functions.
This is part of a longer term rework Alexandru is driving towards.
* bh1750
- Fix up a static compiler warning and make the code more readable.
- yaml conversion of binding + MAINTAINERS entry.
* bmp280
- Drop a stray newline.

First set of IIO new device support, cleanups and features for the 5.5 cycle
Third version with the adis rework set dropped as better to just have
a fresh version of that at some future date.
The usual mixed backs of new device support being added to drivers,
long term reworks continuing and little per driver cleanups and
features.
Also a few trivial counter subsystem tidy ups on behalf of William.
Core new feature
* Device label support. A long requested feature no one got around to
implementing before. Allows DT based provision of a 'label' that
identifies a device uniquely within a system. This differs from existing
'name' which is meant to be the part number.
New device support
* ingenic-adc
- Support for the JZ4770 SoC ADC including bindings.
* inv_mpu6050
- Add support for magnetometer in MPU925x parts.
Fiddly to do as this is actually a separate device sitting inside the
package, but with the master device being able to schedule reads etc.
Will only run if the auxiliary bus is not in use for any other devices.
Features
* ad7192
- Userspace calibration controls to do zero and full scale.
* st_lsm6dsx
- Enable latched interrupts by default for sensors events with related clear.
- Motion events and related wakeup source. This needed quite a bit of
refactoring as well.
Cleanups and minor features
* ad7192
- sysfs ABI docs
* ad7949
- Remove code to readback configuration word as driver never actually enabled
it.
- Fix incorrect xfer length. Not actually known to cause problems other
than wasted bus usage.
* adis16080
- Replace core mlock usage with local lock with more appropriate scope.
* adis16130
- Remove pointless mlock usage.
* adis16240
- Remove include of gpio.h as no gpio usage.
* atlas-ph-sensor
- Improve logical ordering of buffer predisable / postenable functions.
This is part of a longer term rework Alexandru is driving towards.
* bh1750
- Fix up a static compiler warning and make the code more readable.
- yaml conversion of binding + MAINTAINERS entry.
* bmp280
- Drop a stray newline.
* cm36651
- Drop a redundant assignment
* itg3200
- Alignment cleanup.
* max31856
- Add missing of_node and parent references, useful to identify the device.
* sc27xx_adc
- Use devm_hwspin_lock_request_specific rather than local rolled version.
* stm32-lptimer counter
- kernel-doc warning.
