iio: impedance-analyzer: New driver for AD5933/4 Impedance Converter, Network Analyzer

The AD5933 is a high precision impedance converter system solution
that combines an on-board frequency generator with a 12-bit, 1 MSPS,
analog-to-digital converter (ADC). The frequency generator allows an
external complex impedance to be excited with a known frequency.

The response signal from the impedance is sampled by the on-board ADC
and a discrete Fourier transform (DFT) is processed by an on-chip DSP engine.
The DFT algorithm returns a real (R) and imaginary (I) data-word at each
output frequency.

Changes since V1:

Apply list review feedback:
Consistently use poll_time_jiffies.
Use be|le cpu endian helpers where applicable.
Add various comments.

Changes since V2:

Fix KernelVersion tag in Documentation.
Declare ad5933_default_pdata static.
Fix typos.

Merge tag 'iio-for-5.2a-2' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

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

support.
* mxs-lradc-adc
- Handle devm_iio_trigger_alloc failure.
* sps30

* 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
