1st set of IIO new device support, features and cleanups for the 6.3 cycle

The usual mixed bag. So far this has been a quiet cycle for IIO.

New device support
* adi,ad8686
  - Add support for the AD5337 DAC - ID and 8 bit channel support.
* maxim,max5522
  - New driver for this 2 channel DAC.
* nxp,imx93-adc
  - New driver for this SoC ADC which is a fresh IP that will probably
    turn up in additional SoCs going forwards.
* st,magn
  - Add support for magnetometer part of LSM303C which is very similar
    to standalone LIS3MDL already supported.
* ti,ads7924
  - New driver for this 4 channel, 12-bit I2C ADC.
* ti,lmp92064
  - New driver for this 12 bit SPI ADC.
* ti,tmag5273
  - New driver for this 3D Hall-Effect Sensor.

Features
* core
  - Add a standard structure for the value pairs in IIO_VAL_INT_PLUS_MICRO
    available attributes and similar.
* cirrus,ep93xx
  - Add DT binding docs and convert driver to DT based probing.
  - Enable testing building with CONFIG_COMPILE_TEST.
* st,stm32-dfsdm
  - Enable ID register support for discovery of hardware capabilities on
    some devices.

Cleanups and minor fixes
* core
  - Drop the custom iio_sysfs_match_string_with_gaps().
    The special ability of this function to skip gaps in an array
    was never used by any upstream driver.
  - Sort headers whilst touching this file.
* tools
  - Fix memory leak in iio_utils.c
* various
  - leftover i2c probe_new() conversions.
  - scnprintf() -> sysfs_emit() cleanups.
  - hand rolled devm enables -> devm_regulator[_bulk]_get_enable()
  - typo fixes
  - dt-binding cleanup (whitespace, excess quotes and similar)
* adi,ad7746
  - Set variable without pointless conditional.
* fsl,mma9551
  - Squash false positives about use of uninitialized variable where
    garbage undergoes an endian conversion before being ignored.
* measspec,ms5611
  - Switch to fully devm_ managed probe() and so drop explicit remove()
* qcom,spmi-adc
  - Use dev_err_probe() to suppress deferred print.
* qcom,spmi-adc5
  - Define a missing channel used for battery identification.
* qcom,spmi-iadc
  - Document a compatible seen in wild.
* semtech,sx9360
  - Fix units on semtech,resolution dt-binding.
* sensiron,scd30
  - dev_err_probe() usage to simplify error paths a little.
* st,lsm6dsx
  - Add missing mount matrix for the gyro IIO device.
* taos,tsl2563
  - Respect firmware configured interrupt polarity if present.
  - Use i2c_smbus_write_word_data() in a few cases not previously covered.
  - Factor out duplicated interrupt configuration.
  - Switch to GENMASK() / BIT() from hand coded equivalents.
  - Tidy up unused definitions.
  - Use dev_err_probe() as appropriate.
  - Drop platform_data as no in kernel users and there are better ways to
    do equivalent if any are added.
  - Add local struct device variable to tidy up code.
  - Avoid dance via i2c_client to get the drvdata.
  - Tidy up headers ordering and Makefile ordering.
* ti,adc128s052
  - Use new spi_get_device_match_data().
  - Drop ACPI_PTR() protection.
  - Sort headers whilst here.
  - Use asm instead of incorrect include of asm-generic/unaligned.h
* vishay,vcn4000
  - Interrupt support for vcnl4040 (lots of refactoring needed)
* xilinx,ams
  - Use fwnode_device_is_compatible() instead of open coding it.

description:
The ADC on iMX93 is a 8-channel 12-bit 1MS/s ADC with 4 channels
connected to pins. it support normal and inject mode, include
One-Shot and Scan (continuous) conversions. Programmable DMA
enables for each channel Also this ADC contain alternate analog
watchdog thresholds, select threshold through input ports. And
also has Self-test logic and Software-initiated calibration.

title: TI TMAG5273 Low-Power Linear 3D Hall-Effect Sensor
maintainers:
- Gerald Loacker <gerald.loacker@wolfvision.net>
description:
The TI TMAG5273 is a low-power linear 3D Hall-effect sensor. This device
integrates three independent Hall-effect sensors in the X, Y, and Z axes.
The device has an integrated temperature sensor available. The TMAG5273
can be configured through the I2C interface to enable any combination of
magnetic axes and temperature measurements. An integrated angle calculation
engine (CORDIC) provides full 360° angular position information for both
on-axis and off-axis angle measurement topologies. The angle calculation is
performed using two user-selected magnetic axes.
