1st set of new IIO/counter device support, features and cleanup for 5.14

There are a couple of large cleanup sets in here alongside a number of new
drivers.

Note an immutable branch merged to add a stub for i2c_verify_client()
as needed to avoid a build issue in the fxls8962af driver as a result of a
workaround for a device errata that only applies when i2c interface is used.

Counters
========

New device support
* intel,quadrature encoder peripheral found on Elkhart Lake platforms.
  - New driver.

IIO
===

New device support
* amstaos,tsl2591 ambient light sensor.
  - New driver + bindings
  - Follow up fix to ensure some local variables are suitable for error
    handling.
* fsl,fxls8962af + fsl,fxls8964af accelerometers
  - New driver + bindings
  - Includes an errata work around that cause a build bot failure fixed
    by adding a stub to i2c.
* kionix,kxcjk-1013
  - Add support for KX023-1025 device.  Mostly a different register map
    that needed to be supported.
* murata,sca3300 accelerometer
  - New driver + bindings
* st,lsm9ds0 IMU
  - Rework of st,sensors driver to cleanly support this new glue driver
    that enables the two parts of the LSM9DS0.
* ti,tsc2046 touchscreen controller ADC.
  - New driver. Intent here is to use this with existing IIO consumer
    drivers such as resistive-adc-touch.
  - Follow up fix to avoid an issue with unsigned subtraction in error
    check.
* ti,tmp117 digital temperature sensor
  - New driver + bindings

Features
* adi,ad5755
  - Add missing dt-binding doc
* adi,ad7298
  - Add ACPI ID used on Intel Galileo Gen 1 boards.
  - Add missing dt-binding doc
* adi,ad7476
  - Add missing dt-binding doc
* adi,ad7746
  - Add missing dt-binding doc for this driver that will hopefully move out
    of staging shortly. Update staging driver to use the binding instead of
    platform data.
* adi,adis16201 + adis16209
  - Add missing dt-binding doc
* adi,adis16480
  - Support burst mode for adis16495 and adis16497 parts.
* bosch,bma220
  - Add missing dt-binding doc
* fsl,mma7455
  - Add missing dt-binding doc
* iio-rescale
  - Support handling of processed channels from provider.  Some ADCs
    require (typically non linear) calibration functions to be applied,
    and so provide only IIO_CHAN_INFO_PROCESSED read back. They can be
    used as providers to the iio-rescale driver which needs to handle them
    somewhat differently from IIO_CHAN_INFO_RAW
* sensiron,sps30
  - Support the serial interface.  Note this required significant
    refactoring of existing driver.
* st,st-sensors
  - Add mount matrix support for normal dt-binding whilst continuing to
    support the odd ACPI approach for accelerometers.
* ti,dac082s085 + similar
  - Add missing dt-binding doc
* trivial-devices - add entries for
  - memsic,mx4005, memsic,mx6255 and memsic,mxc6655
  - sensortek,stk8312 and sensortek,stk8ba50

Cleanup / minor fixes
* core
  - Use devm_add_action_or_reset() to replace boilerplate in several
    driver and core IIO devm_* functions.
  - Fix an error path issue introduced by above, that could return an
    error pointer rather than the expected null from dev_iio_device_alloc()
  - Move more IIO internals related fields from struct iio_dev to
    struct iio_dev_opaque.
  - Drop unused final update of in_loc in demux setup.
* Docs
  - Move some docs from driver specific to core dos to avoid replication
    of names which the documentation builder does not allow.
    Note this means adding a few device specific notes to the general docs
    to cover the more unusual uses of the ABI.
  - ABI: Move old buffer/* and scan_elements/* docs to obsolete as now we
    have the bufferX/* variant.  Not we are not getting rid of these
    interfaces, just encouraging new code to use the new interface.
* IIO wide:
  - Tidy up new cases of dev.parent etc being set in drivers as the core
    now does it.
  - Fix more cases of possible miss-aligned buffers when passed to
    iio_push_to_buffers_with_timestamp().  Note we only have one known
    instance of anyone seeing this bug actually happening, so this has been
    a low priority cleanup effort for several cycles.
  - sysfs_emit() used in more drivers.
  - Runtime pm tidy up and use of pm_runtime_resume_and_get()
  - Buffer alignment fixes as iio_push_to_buffers_with_timestamp requires
    that the timestamp when inserted by naturally aligned + consumers can
    assume that all fields are naturally aligned. Part of a long running
    effort, with at least 2 more series to come tackling additional
    variants.
  - Stop specifying "mount-matrix" property name in every lookup of the
    mount matrix from firmware by hard coding it in the core.
* adi,ad7476
  - Handle the variety of different regulators used by the parts supported
    by this driver (came up in dt-binding review)
* adi,ad7746
  - Trivial drop of if (ret) return ret; return 0; pattern
  - Tidy up comments
  - Pull capdac setup out to own function.
* adi,ad7766
  - Trivial drop of if (ret) return ret; return 0; pattern
* adi,adis
  - Avoid returning error codes in interrupt handlers.
  - Handle a failure in spi_write in the trigger handler.
  - Rework to add updating of device page after changing it.
  - Don't push data to IIO buffers when read failed.
  - Add configuration of burst max speed to core avoid handling this in
    each driver.
  - Use the adis_dev_lock() helper in adis16260 and adis16136 drivers.
  - Excessive includes cleanup via include-what-you-use static checker
    after zero day highlighted that these needed updating.
* afe
  - Amend binding to add #io-channel-cells, thus allowing this IIO
    consumer to also be an IIO provider.
* aosong,am2315
  - Drop ACPI id. Unlikely this one is in the wild and it isn't valid
    ACPI naming.
* bosch,bma180
  - Adding missing bandwidth settings (500, 1000 Hz)
* bosch,bme680
  - Drop ACPI id. Unlikely this one is in the wild and it isn't valid
    ACPI naming.
* ep93xx_adc,
  - Drop a redundant error print.
* maxim,max118
  - Convert remainder of probe() to devm_ managed functions.
  - Avoid some repeated jumping back and forth between iio_dev and
    spi structures.
* maxim,max11100
  - Use get_unaligned_be16() instead of open coding.
  - Convert remainder of probe() to devm_ managed functions.
* samsung,exynos_adc
  - Unused error value dropped.
* sensiron,sgp30
  - Drop use of %hx in favor of %x and letting the normal type conversion
    work.
* sensortek,stk8312
  - Add lowercase device id and note uppercase version deprecated.
  - Drop ACPI id. Unlikely this one is in the wild and it isn't valid
    ACPI naming.
* sprx,sc72xx_adc
  - add MODULE_DEVICE_TABLE
* st,lsm6dsx
  - Fix docs of valid ODRs
* st,sensors
  - dt-binding rework.  Two efforts on this crossed in a previous cycle
    so this update cherry picks the best of the two yaml conversions.
  - Don't copy the channel spec array as now ext_info is no longer modified.
* st,stm32-adc
  - tidy up some docs that were marked as kernel-doc but aren't.
* ti,adc081c, ti,adc0832, ti,adc108s102 and ti,adc161s626
  - Convert remainder of probe() functions to devm_ managed functions
    to simplify error handing and remove paths.

Description:
Description of the scan element data storage within the buffer
and hence the form in which it is read from user-space.
Form is [be|le]:[s|u]bits/storagebits[>>shift].
be or le specifies big or little endian. s or u specifies if
signed (2's complement) or unsigned. bits is the number of bits
of data and storagebits is the space (after padding) that it
occupies in the buffer. shift if specified, is the shift that
needs to be applied prior to masking out unused bits. Some
devices put their data in the middle of the transferred elements
with additional information on both sides. Note that some
devices will have additional information in the unused bits
so to get a clean value, the bits value must be used to mask
the buffer output value appropriately. The storagebits value
also specifies the data alignment. So s48/64>>2 will be a
signed 48 bit integer stored in a 64 bit location aligned to
a 64 bit boundary. To obtain the clean value, shift right 2
and apply a mask to zero the top 16 bits of the result.
For other storage combinations this attribute will be extended
appropriately.
Since kernel 5.11 the scan_elements attributes are merged into
the bufferY directory, to be configurable per buffer.

Description:
A single positive integer specifying the position of this
scan element in the buffer. Note these are not dependent on
what is enabled and may not be contiguous. Thus for user-space
to establish the full layout these must be used in conjunction
with all _en attributes to establish which channels are present,
and the relevant _type attributes to establish the data storage
format.
Since kernel 5.11 the scan_elements attributes are merged into
the bufferY directory, to be configurable per buffer.
What: /sys/bus/iio/devices/iio:deviceX/buffer/watermark
KernelVersion: 4.2
Contact: linux-iio@vger.kernel.org
Description:
A single positive integer specifying the maximum number of scan
elements to wait for.
Poll will block until the watermark is reached.
Blocking read will wait until the minimum between the requested
read amount or the low water mark is available.
Non-blocking read will retrieve the available samples from the
buffer even if there are less samples then watermark level. This
allows the application to block on poll with a timeout and read
the available samples after the timeout expires and thus have a
maximum delay guarantee.
Since Kernel 5.11, multiple buffers are supported.

buffer. In the case of an output buffer, this indicates the
amount of empty space available to write data to. In the case of
an input buffer, this indicates the amount of data available for
reading.

The ADF4371 has an integrated VCO with fundamendal output
frequency ranging from 4000000000 Hz 8000000000 Hz.
out_altvoltage0_frequency:
A divide by 1, 2, 4, 8, 16, 32 or circuit generates
frequencies from 62500000 Hz to 8000000000 Hz.
out_altvoltage1_frequency:
This channel duplicates the channel 0 frequency
out_altvoltage2_frequency:
A frequency doubler generates frequencies from
8000000000 Hz to 16000000000 Hz.
out_altvoltage3_frequency:
A frequency quadrupler generates frequencies from
16000000000 Hz to 32000000000 Hz.
Note: writes to one of the channels will affect the frequency of
all the other channels, since it involves changing the VCO
fundamental output frequency.
