Jonathan writes:

Second set of IIO new device support, features and cleanup for the 4.14 cycle.

New device support:
* ak8974
  - support the AMI306.
* st_magnetometer
  - add support for the LIS2MDL with bindings.
* rockchip-saradc
  - add binding for rv1108 SoC (no driver change).
* srf08
  - add srf02 (i2c only) and srf10 support.
* stm32-timer
  - support for the STM32H7 to existing driver.

Features:
* tools
  - move over to the tools buildsystem rather than hand rolling.
  - add an install section to the build.
* ak8974
  - use serial number to add device randomness.
  - add AMI306 calibration data output.
* ccs811
  - triggered buffer support.
* srf08
  - add a device tree table as the old style i2c probing is going away,
  - add triggered buffer support
* st32-adc
  - add optional st,min-sample-time-nsecs binding to allow control of
    sampling against analog circuitry.
* stm32-timer
  - add output compare triggers.
* ti-ads1015
  - add threshold event support.
* ti-ads7950
  - Allow use on ACPI platforms including providing a default reference
    voltage as there is no way to obtain this on ACPI currently.

Cleanup and fixes:
* ad7606
  - fix an error return code in probe.
* ads1015
  - fix incorrect data rate setting update when capture in progress,
  - fix wrong scale information for the ADS1115,
  - make conversions work when CONFIG_PM is not set,
  - make sure we don't get a stale result after a runtime resume by
    ensuring we wait long enough,
  - avoid returning a false error form the buffer setup callbacks,
  - add enough wait time to get the correct conversion,
  - remove an unnecessary config register update,
  - add a helper to set conversion mode reducing repeated boilerplate,
  - use devm_iio_triggered_buffer_setup to simplify error and remove
    paths,
  - use iio_device_claim_direct_mode instead of opencoding the same.
* ak8974
  - mark the INT_CLEAR register as precious to prevent debugfs access.
* apds9300
  - constify the i2c_device_id.
* at91-sama5 adc
  - add missing Kconfig dependency.
* bma180 accel
  - constify the i2c_device_id.
* rockchip_saradc
  - explicitly request exclusive reset control as part of the reset rework
    on going throughout the kernel.
* st_accel
  - fix drdy configuration for a load of accelerometers that only have
    the int1 line.  Fix is unimportant as presumably no deviec tree actually
    used the non existent hardware line.
* st_pressure
  - fix drdy configuration for LPS22HB and LPS25H by dropping int2 support
    as they don't have this. Fix is unimportant as presumably no device tree
    actually used the non existent hardware line.
* stm32-dac
  - explicitly request exclusive reset control (part of reset being reworked).
* tsl2583
  - constify the i2c_device_id.
* xadc
  - coding style fixes.
