    First set of new device support, features and cleanups for IIO in the 5.6 cycle
    
    New device support
    
    * ad7091r5 ADC
      - New driver with follow up patch adding scale and vref support.
      - DT bindings
    * ad7923
      - Support for ad7908, ad7918 and ad7928 added to driver.
    * bma180
      - Support the BMA254 accelerometer. Required fairly substantial rework
        to allow for small differences between this an existing parts.
    * bma400 accelerometer
      - New driver with follow up patch for regulator support.
      - DT bindings.
    * asc dlhl60d
      - New driver support this range of pressure and temperature sensors.
      - DT bindings.
    * ltc2496 ADC
      - New driver to support this ADC.
      - Split the existing LTC2497 driver generic component out and reuse.
      - DT bindings.
    * parallax ping
      - New driver supporting ultrasonic and laser tof distance sensors.
      - Bindings for these sensors.
    
    New features
    
    * core
      - New char type for read_raw returns, used for thermocouple types.
      - Rename read_first_n callback to read.   The reasons behind the original
        naming are lost to the mists of time.
    * ad799x
      - Allow pm_ops to disable device completely allowing regulator power down.
    * bma180
      - Enable basic regulator support.
    * dmaengine buffer
      - Report platform data alignment requirements via new ABI.
    * max31856
      - Add option to set mains filter rejection frequency and document
        new in_temp_filter_notch_center_frequency ABI.
      - Add support for configuring HW averaging (oversampling ratio)
      - Add runtime configuration of thermocouple type and document new ABI.
    * maxim-thermocouple
      - Add read only access to thermocouple type using new ABI, includes
        adding more specific compatibles to reflect which variant of the
        chip is being used.
    * mpu6050
      - Provide option to support the PMU9150 in package magnetometer directly
        rather than via auxiliary bus.
    * stm32_adc
      - Add overrun interrupt checks to detect if this happens.
    * st_lsm6dsx
      - Enable the sensor-hub support for lsm6dsm. Includes various reworks to
        allow this.
    
    Cleanups and minor fixes
    
    * Subsystem wide
      - Tidy up indentation in Kconfig and fix alphabetical order of AD7091R5.
      - Drop linux/gpio.h and linux/of_gpio.h from drivers that don't use them.
    * ad7266
      - Convert to GPIO descriptors.
    * ad7303
      - Avoid a dance with checking if the regulator is supplied by just
        using the optional request interface.
    * ad7887
      - Simplify channel specification assignment to enable adding more devices.
    * ad7923
      - Drop some unused and largely pointless defines of BOB_N==N variety.
      - Tidy up checkpatch warnings.
      - Add missing of_device_id table.
    * adf4350
      - Convert to GPIO descriptors.
    * ak8975
      - Convert to GPIO descriptors.
    * ADIS library and drivers
      - Expand scope of txrx_lock to cover all state and rename as state_lock
      - Add unlocked read / write to allow grouping of consecutive calls under
        single lock / unlock.
      - Add unlocked check_status, reset to allow grouping under single
        lock / unlock.
      - Remove remaining uses of core mlock for local state protection.
        mlock should never be used directly as it protects tightly defined
        core IIO device management state.
    * adis16240
      - Enforce only supported SPI mode on driver load + add DT binding doc.
    * atlas-ph-sensor
      - Rename to atlas-sensor given it now covers things beyond ph sensors.
    * bma180
      - Use local dev variable to tidy up code.
      - Use c99 style explicity .member assignment to make driver more readable.
    * bmp280
      - Drop ACPI support. No evidence this was used and appropriate ID is not
        registered.
      - Allow ACPI to bind device via PRP0001
    * dmaengine buffer
      - Use dma_request_chan instead of dma_request_slave_channel_reason as that
        ABI is going away.
      - Add module info to avoid tainting the kernel.
    * hts221
      - Avoid magic number defines when only used to fill structure elements
        that are self describing.
    * lm3533
      - Drop a stray semicolon.
    * max9611
      - Cleanup enum handling to be more resilient to future changes.
    * mpu6050
      - Delete MPU9150 from supported SPI devices as doesn't provide SPI.
      - Select I2C_MUX again after kbuild issue fixed elsewhere.
    * stm32-timer
      - Drop an unnecessary register update.
    * ssp_sensors
      - Convert to GPIO descriptors.
    * st_sensors
      - drop !CONFIG_ACPI defines as ACPI_PTR() will stop them being used
        anyway.
      - Make default platform data structures __maybe_unsued.
      - Fill in some missing kernel-doc function parameters.
    * st_lsm6dsx
      - white space fixes.
      - Mark some constants that aren't always used as __maybe_unused.
      - Drop of ID table guards as they just pervent use under ACPI.
      - Switch to device properties to allow ACPI usage.
    * st_uvis25
      - Drop acpi.h include as no ACPI APIs used.
    * ti-ads1015
      - Drop legacy platform data as no one seems to be using it.
      - Use the device property API instead of OF specific.
    * ti-ads7950
      - typo fix in error message.
