Second set of features and cleanups for IIO in 5.10

We have a couple of changes that apply to large sets of drivers, so
I have grouped those to keep this short.

There are a few late breaking fixes in here that can wait for the
merge window.

dt yaml conversions
-------------------

* ti,ads7950
* ti,twl4030-madc

Features
--------

* adxrs290
  - Add triggered buffer support and expose data ready signal as a possible
    trigger. Includes updating bindings.
  - Add debugfs hooks for register access.
* mlx90632
  - Add a clear user interface to override the measured ambient temperature.
* vl53l0x
  - Add IRQ support including dt bindings.

Cleanups and minor fixes
------------------------
(groups)
Replace mlock with local lock:
  * adf4350
  * exynos-adc
  * fls-imx25-gcq
  * stm32-dac

devm use to simplify probe error handling and remove functions.
  * adis16201
  * adis16203
  * adis16209
  * adis16240
  * adis16136
  * adis16260
  * adis16400
  * adis16460
  * adis16480
  * adis library - drop unused adis_setup_buffer_and_trigger()

of_match_ptr removal and incorrect ACPI binding removal
  of_match_ptr() rarely makes sense in an IIO driver as space saving
  is trivial and it breaks ACPI PRP0001 based instantiation.
  Mostly this series is about removing examples that get copied into new
  drivers.
  * ad2s1200
  * ad5272
  * ad5446
  * ad5592r
  * ad5593r
  * ad5703

  * ad7303
  * ad7947
  * adis16080
  * adis16400
  * iio_dummy_evgen
  * sgp30

Fixes for buffer alignment when passed to iio_push_to_buffers_with_timestamp()
This is a long running effort.  There are a few more drivers to come.
  * inv_mpu6050
  * itg3200
  * si1145
  * st_lsm6dsx
  * ti-adc0832
  * ti-adc12138

(not driver focused)
* MAINTAINERS
  - Consolidate Analog Device IIO entries whilst removing Beniamin Bia.
  - Remove Hartmut Knaack as a listed IIO maintainer as he hasn't been
    active for a long time and people are getting intermitted bounces.
* Add __printf() markings to a few functions that were missing them.
* drop some rotted documentation from staging.
* rework buffer sysfs file creation (precursor to multiple buffer support)

(individual drivers)
* ad5592r
  - Fix use of true for IIO_SHARED_BY_TYPE
  - Tidy up locking and indentation.
* ad9467
  - Improve error message on chip-id missmatch.
  - Use more appropriate error value if chip-id not recognised.
* adis-library
  - Simplify burst mode handling.
* adxrs290
  - Make sure to switch device to standby mode during remove.
* as73211
  - Increase measurement timeout as seems some devices are slower.
* bma180
  - Fix use of true fo IIO_SHARED_BY_TYPE
* exynos_adc
  - Update binding to require second interrut with touch screen.
  - Update binding to not require syscon on S5Pv210
* hmc5843
  - Fix use of true for IIO_SHARED_BY_TYPE
* inv_mpu6050
  - Use regmap_noinc_read() for fifo reading.
* palmas_gpadc
  - Use module_platform_driver() to remove boilerplate.
* meson-saradc
  - style consistency fixes
* rockchip_saradc
  - Allow compile testing with !ARM.
* st_lsm6dsx
  - Changing scaling factor to use IIO_VAL_INT_PLUS_NANO to improve precision.
  - Fix an issue with unchecked return value.
* stm32-adc
  - Fix a missing return introduced in dev_err_probe() patch earlier in
    cycle.
* sx9310
  - Prefer async mode for probe as paticularly slow startup.

-Freescale i.MX25 ADC GCQ device
-
-This is a generic conversion queue device that can convert any of the

-
-Required properties:
- - compatible: Should be "fsl,imx25-gcq".
- - reg: Should be the register range of the module.
- - interrupts: Should be the interrupt number of the module.
-   Typically this is <1>.
- - #address-cells: Should be <1> (setting for the subnodes)
- - #size-cells: Should be <0> (setting for the subnodes)
-
-Optional properties:
- - vref-ext-supply: The regulator supplying the ADC reference voltage.
-   Required when at least one subnode uses the this reference.
- - vref-xp-supply: The regulator supplying the ADC reference voltage on pin XP.
-   Required when at least one subnode uses this reference.
- - vref-yp-supply: The regulator supplying the ADC reference voltage on pin YP.
-   Required when at least one subnode uses this reference.
-
-Sub-nodes:
-Optionally you can define subnodes which define the reference voltage
-for the analog inputs.
-
-Required properties for subnodes:
- - reg: Should be the number of the analog input.

-Freescale vf610 Analog to Digital Converter bindings
-
-The devicetree bindings are for the new ADC driver written for
-vf610/i.MX6slx and upward SoCs from Freescale.
-
-Required properties:
-- compatible: Should contain "fsl,vf610-adc"
-- reg: Offset and length of the register set for the device
-- interrupts: Should contain the interrupt for the device
-- clocks: The clock is needed by the ADC controller, ADC clock source is ipg clock.
-- clock-names: Must contain "adc", matching entry in the clocks property.
-- vref-supply: The regulator supply ADC reference voltage.
-
-Recommended properties:
-- fsl,adck-max-frequency: Maximum frequencies according to datasheets operating
-  requirements. Three values are required, depending on conversion mode:
-  - Frequency in normal mode (ADLPC=0, ADHSC=0)
-  - Frequency in high-speed mode (ADLPC=0, ADHSC=1)
-  - Frequency in low-power mode (ADLPC=1, ADHSC=0)
-- min-sample-time: Minimum sampling time in nanoseconds. This value has
-  to be chosen according to the conversion mode and the connected analog
-  source resistance (R_as) and capacitance (C_as). Refer the datasheet's
-  operating requirements. A safe default across a wide range of R_as and
-  C_as as well as conversion modes is 1000ns.
-
