First set of new device support, features and fixes for IIO in the 5.2 cycle

Staging graduations
* ad7780
  - Move this ADC driver out of staging.  Included adding some new features
    along the way (see below). Also added DT bindings.

New device support
* adis16480
  - Support the ADIS16495 and ADIS16497 IMU devices making
    heavy use of refactoring of various aspects of the driver in precursor
    patches.
* lsm6dsx
  - Support for the ASM330LHH 6-axis (accelerometer + gyro) sensor.
  - Support for the LSM6DS0X
* matbotix mb1232
  - New driver for this ultrasound ranging device family. Including bindings.
  - Supports mb1202, mb1212, mb1222, mb1232, mb1242, mb7040 and mb7137.
* max31856
  - New driver for this thermocouple temperature sensor.
* meson saradc
  - Support the Meson-G12A (ID addition only).
* stmpe-adc
  - New driver supporting generic ADC alongside touchscreen support which
    previously existed. Includes DT bindings.
* vcnl4000
  - Support for the vcln4040 proximity and light sensor, including adding
    DT bindings for this and parts previously supported.

Features
* core
  - Allow reading of mount matrices from ACPI in addition to DT.
  - Common binding for theromcouple types.
* ad5933
  - Add ABI docs as there are a few 'unsual' elements about this
    device - perhaps because it's our only impedance analyser.
* ad7780
  - Add gain and filter gpio support + readback of current gain and filter.
* adis16480
  - Allow selection fo the dataready pin to be used.
  - Device tree ID table and binding documentation.
  - Support external clock modes, including new bindings.
* bma180
  - Mount matrix support.
* bmc150
  - Mount matrix support.
* bmg160
  - Mount matrix support.
  - DT id table and bindings doc.
* bmp280
  - Put calibration data into the entropy pool.
* hmc5843
  - Mount matrix support.
* itg3200
  - Mount matrix support.
* kxcjk1013
  - Device tree id table, and binding docs.
* lpc32xx
  - Add scale when regulator specified including DT docs for regulator.
* pms7003
  - Add device IDs for all supported parts to driver and binding.
* stm32-dfsdm
  - Enable hw consumer support, scan mode control and a complex set of
    triggered buffer modes.
  - Power management.
* stm32-lptimer-counter
  - power management.
  - Document the pinctrl sleep state binding.
* ti-ads7950
  - GPIO pin support.

Cleanups, minor fixes
* core
  - Use bitmap_zalloc to make it explicit that is what we are doing.
  - Tidy up all the Kconfig files (which had slowly gotten messy)
  - Fix a forwards definition missing issue in iio/driver.h
* ad sigma delta core
  - Improve handling of SPI bus locking vs CS assertion.  This has been
    wrong a long time so not rushing this in.
* ad5064
  - Mlock to local lock.
* ad5933 (staging cleanup)
  - Multiline comment fixes.
  - Include ordering.
  - SPDX.
  - Tidy up Kconfig help which was a bit missleading.
  - Change some non standard attributes to ABI defined ones.
* ad7124
  - White space fix.
* ad7192
  - White space.
  - Use DT clock binding.
  - Improve error reporting.
  - Platform data to DT conversion.
  - Use read_avail callback, mostly to avoid the endless series of
    patches from new contributors trying to falsely put spaces around
    the negative sign.
* ad7280a
  - Add brackets to macros to avoid potential precedence isseus.
  - Add temp vars for event codes to reduce indent and improved readability.
  - Clean out som CamelCase notation.
  - White space.
* ad7606
  - Fix broken file naming in MAINTAINERS.
* ad7780
  - Missing switch defaults to supress warnings and harden the code slightly.
  - Set pattern masks more directly.
  - Add ID values and masks for all supported chips.
  - SPDX + add Renato as a copyright holder as he has done a lot of work on
    this driver.
  - Add brackets to macros to avoid potential precedence issues.
* ad7923
  - White space fixes.
  - Use BIT macro to improve readability.
  - Add brackets to macros to avoid potential precedence issues.
  - Tidy up a null comparisom.
* ad9523
  - Fix a typo in naming of variables.
* adis16400
  - Combine trigger file into main code as no advantage in separate files.
    Rename core file to just adis16400.
  - Squash the header into the c file now there is only one file.
  - Generalize burst mode to support new variants.
* ak8975
  - Local variable to improve readability around mount matrix support.
* as3935
  - Avoid potential race by ensuring remove does exact opposite of
    probe rather than a slightly different order.
* cross_ec
  - Drop some unnecessary includes.
  - Fix some warning and the slightly 'unusual' code.
  - Add some docs for non obvious function.
  - SPDX
* hmc5843
  - Potential unhandled error case.
* iio trigger core
  - Print an error if there is no available irq due to max consumers per
    trigger being set to low.
* iio loop trigger
  - Drop an unlikely on IS_ERR as IS_ERR already has the annotation.
* ingenic-adc
  - Drop a redundant dev_err call as devm_ioremap_resource reports the same
    internally.
* lmp91000
  - Drop some unncessary parentheses and white space tidy up.
  - Invert and if statement to improve readability.
  - Fix a wrong error message.
* lpc32xx
  - Header sorting + drop some unused ones.
* mma8542
  - Mark a switch fallthrough.
* mpu6050
  - Add a local variable to improve code readability around mount matrix
    support.
* mxs-lradc-adc
  - Handle devm_iio_trigger_alloc failure.
* sps30
  - Fix up a kernel version in the ABI docs.
* srf04
  - DT binding doc converted to yaml.
* ssp_sensors
  - Supress a clang build warning due to lack of visibility of conditional
    within a iio_push_to_buffers_with_timestamp.  (reasonable false warning!)
* st_accel
  - Drop pointless less than 0 comparisom of unsigned int.
* stm32-dfsdm
  - Improve accuracy of spi_master_frequency calculation.
  - Improve calculation fo sampling frequency.
  - Rework various internals to simplify adding triggered buffer support.
  - Claim direct mode to avoid racing around read_raw and being in buffered
    mode.
* stmpe
  - Fix a clang false positive warning.
* ti-ads7950
  - Use local lock rather than using the core mlock when not locking around
    the device mode.
* vcnl4000
  - Use word writes instead of byte writes.  It seems byte writes are fine
    for some parts (undocument) but not others that the driver will shortly
    support.

Other
* mailmap
  - Add email address change for Sean Nyekjaer.  Update in relevant drivers
