IIO: New device support, features and cleanup for the 6.20/7.0 cycle.

Slightly messier than normal unfortunately due to some conflicts
and build config bugs related to I3C drivers.

One last minute Kconfig fix right at the top after a linux-next report.
I've simplified the Kconfig and made it match other instances in the kernel
so that should be safe enough despite short soak time in front of build bots.

Merge of an immutable branch from I3C to get some stubs that were missing
and caused build issues with dual I2C / I3C drivers. This also brought in a
drop of some deprecated interfaces so there is also one patch to update a
new driver to not use those.

We are having another go at using cleanup.h magic with the IIO mode claim
functions after backing out last try at this. This time we have wrappers
around the new ACQUIRE() and ACQUIRE_ERR() macros.
Having been burnt once, we will be taking it a bit more slowly this time
wrt to wide adoption of these! Thanks in particular to Kurt for taking
on this core IIO work.

New Device Support
==================

adi,ad18113
- New driver to support the AD18113 amplifier - an interesting device due
  to the external bypass paths where we need to describe what gain those
  paths have in DT. Longer term it will be interesting to see if this
  simplistic description is enough for real deployments.
adi,ad4062
- New driver for the AD4060 and AD4052 SAR ADCs including trigger, event
  and GPIO controller support.  Follow up patch replaced use of some
  deprecated I3C interfaces prior to the I3C immutable branch merge as
  that includes dropping them.
adi,ad4134
- New driver for the AD4134 24bit 4 channel simultaneous sampling ADC.
adi,ad7768-1,
- Add support for the ADAQ767-1, ADAQ7768-1 and ADAQ7769-1 ADCs after some
  rework to enable the driver to support multiple device types.
adi,ad9467
- Add support for the similar ad9211 ADC to this existing driver.
- Make the selection of 2s comp mode explicit for normal operation and
  switch to offset binary when entering calibration mode.
honeywell,abp2
- New driver to support this huge family (100+) of board mount pressure and
  temperature sensors.
maxim,max22007
- New drier for this 4 channel DAC.
memsic,mmc5633
- New driver for this I2C/I3C magnetometer. Follow on patches fixed up
  issues related to single driver supporting both bus types.
microchip,mcp747feb02
- New driver for the Microchip MCP47F(E/V)B(0/1/2)1,
  MCP47F(E/V)B(0/1/2)2, MCP47F(E/V)B(0/1/2)4 and MCP47F(E/V)B(0/1/2)8
  buffered voltage output DACs.
nxp,sar-adc
- New driver support ADCs found on s32g2 and s32g3 platforms.
ti,ads1018
- New drier for the ADS1018 and ADS1118 SPI ADCs.
ti,ads131m02
- New driver supporting ADS131M(02/03/04/06/08)24-bit simultaneous sampling
  ADCs.

Features
========

iio-core
- New IIO_DEV_ACQUIRE_DIRECT_MODE() / IIO_DEV_ACQUIRE_FAILED() +
  equivalents for the much rarer case where the mode needs pinning
  whether or not it is in direct mode.  These use the ACQUIRE()
  / ACQUIRE_ERR() infrastructure underneath to provide both simple
  checks on whether we got the requested mode and to provide scope
  based release. Applied in a few initial drivers.
adi,ad9467
- Support calibbias control
adi,adf4377
- Add support to act as a clock provider.
adi,adxl380
- Support low power 1KHz sampling frequency mode. Required rework of
  how events and filters were configured, plus applying of constraints
  when in this mode.
rf-digital,rfd77402
- Add interrupt support as alternative to polling for completion.
st,lsm6dsx
- Tap event detection (after considerable driver rework)

Cleanup and Minor Fixes
=======================

More minor cleanup such as typos, white space etc not called out except
where they were applied to a lot of drivers.

Various drivers.
- Use of dev_err_probe() to cleanup error handling.
- Introduce local struct device and struct device_node variables to
  reduce duplication of getting them from containing structs.
- Ensure uses of iio_trigger_generic_data_rdy_poll() set IRQF_NO_THREAD
  as that function calls non threaded child interrupt handlers.
- Replace IRQF_ONESHOT in not thread interrupt handlers with
  IRQF_NO_THREAD to ensure they run as intended. Drop one unnecessary case.
iio-sw-device/trigger.
- Constify configs_group_operations structures.
iio-buffer-dma / buffer-dma-engine
- Use lockdep_assert_held() to replace WARN_ON() to check lock is
  correctly held.
- Make use of cleanup.h magic to simplify various code paths.
- Make iio_dma_buffer_init() return void rather than always success.

adi,ad7766
- Replace custom interrupt handler with iio_trigger_generic_data_rdy_poll()
adi,ad9832
- Drop legacy platform_data support.
adi,ade9000
- Add a maintainer entry.
adi,adt7316
- Move to EXPORT_GPL_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() so the compiler
  can cleanly drop unused pm structures and callbacks.
adi,adxl345
- Relax build constraint vs the driver that is in input so both may be
  built as modules and selection made at runtime.
adi,adxl380
- Make sure we don't read tail entries in the hardware fifo if a partial
  new scan has been written.
- Move to a single larger regmap_noinc_read() to read the hardware fifo.
aspeed,ast2600
- Add missing interrupts property to DT binding.
bosch,bmi270_i2c
- Add missing MODULE_DEVICE_TABLE() macros so auto probing of modules can
  work.
bosch,smi330
- Drop duplicate assignment of IIO_TYPE in smi330_read_avail()
- Use new common field_get() and field_prep() helpers to replace local
  version.
honeywell,mprls0025pa
  Fixes delayed to merge window as late in cycle and we didn't want to delay
  the rest of the series.
- Allow Kconfig selection of specific bus sub-drivers rather than tying that
  to the buses themselves being supported.
- Zero spi_transfer structure to avoid chance of unintentionally set fields
  effecting transfer.
- Fix a potential timing violation wrt to the chip select to first clock
  edge timing.
- As recent driver, take risk inherent in dropping interrupt direction from
  driver as that should be set by firmware.
- Fix wrong reported number of data bits for channel.
- Fix a pressure channel calculation bug.
- Rework to allow embedding the tx buffer in the iio_priv() structure rather
  than requiring separate allocation.
- Move the buffer clearing to the shared core bringing it into affect for
  SPI as well as I2C.
- Stricter checks for status byte.
- Greatly simplify the measurement sequence.
- Add a copyright entry to reflect Petre's continued work on this driver.
intersil,isl29018
- Switch from spritnf to sysfs_emit_at() to make it clear overflow can't
  occur.
invensense,icm42600
- Allow sysfs access to temperature when buffered capture in use as it
  does not impact other sensor data paths.
invensense,itg3200
- Check unused return value in read_raw() callback.
men,z188
- Drop now duplicated module alias.
rf-digital,rfd77402
- Add DT binding doc and explicit of_device_id table.
- Poll for timeout with times as on datasheet, then replace opencoded
  version with read_poll_timeout().
sensiron,scd4x
- Add missing timestamp channel. The code to push it to the buffer was there
  but there was no way to turn it on.
vti,sca3000
- Fix resource leak if iio_device_register() fails.

+description: |
+  Honeywell pressure sensor of model abp2030pa.
+
+  This sensor has an I2C and SPI interface.
+
+  There are many models with different pressure ranges available. The vendor
+  calls them "ABP2 series". All of them have an identical programming model and
+  differ in the pressure range and measurement unit.
+
+  To support different models one needs to specify its pressure triplet.
+
+  For custom silicon chips not covered by the Honeywell ABP2 series datasheet,
+  the pressure values can be specified manually via honeywell,pmin-pascal and
+  honeywell,pmax-pascal.
+
+  Specifications about the devices can be found at:
+  https://prod-edam.honeywell.com/content/dam/honeywell-edam/sps/siot/en-us/products/sensors/pressure-sensors/board-mount-pressure-sensors/basic-abp2-series/documents/sps-siot-abp2-series-datasheet-32350268-en.pdf
