c55cc97a25 Second set of IIO device support, features, cleanups and minor fixes for 5.3.
A few bits for the counters subsystem mixed in here as well.
 There are some late breaking fixes as well, which aren't so urgent
 they can't wait for the merge window.
 
 New Device Support
 * adf4371
   - New driver + bindings.
   - Support the adf4372 PLL. Mostly ID and bindings.
 * ad8366 (note includes rework of driver needed to allow support for these).
   - Support the ADL5240 variable gain amplifier (VGA).
   - Support the ADA4961 digital gain amplifier (DGA).
 * dps310
   - New driver, in several parts from different authors for this temp
     and pressure sensor.
   - Includes errata workaround for a temperature reading issue.
 * stk3310
   - Support the stk3335, mostly ID.
 
 Features and cleanups
 * core
   - drop error handling on debugfs registration.
   - harden by making sure we don't overrun iio_chan_info_postfix.
 * docs
   - convert remaining docs to rst. At somepoint we'll fit these few
     into the main IIO docs.
   - improve sampling_frequency_available docs but explaining the
     range form.
 * ad_sigma_delta
   - Drop a pointless goto.
 * ad2s1210
   - Drop pointless platform data null check seeing as we don't actually
     use platform data anymore.
 * ad7124
   - Relax limitation on channel numbers to allow pseudo different channels.
   - Support control of whether the input is buffered via DT.
   - Use dynamic allocation for channel configuration to make it easier
     to support new devices.
   - YAML binding conversion.
 * ad7150
   - Comment tidy up.
   - Consistent and simple if (ret) handling of i2c errors.
   - FIELD_GET and GENMASK.
   - Ternary rather than !!(condition) for readability.
   - Use macros to avoid repetition of channel definitions.
 * ad7606
   - Add software channel config (rather that pin controlled)
   - Refactor to simplify addition of new part in future.
 * ad7746
   - of_deivce_id table.
 * ad7780
   - MAINTAINERS entry
   - YAML DT bindings.
 * ad8366
   - Stop using core mlock in favour of well scoped local lock.
   - SPDX + copyright date update.
 * ad9834
   - of_device_id table
 * adf4371
   - Add support for output stage muting before lock on has occured.

   - MAINTAINERS entry to reflect that this now Alexandru's problem ;)
 * adis162xx:
   - Fix a slightly incorrect set of comments and print statements on
     minimum supported voltage.
 * adis16203
   - of_device_id table.
 * adis16240
   - Add of_device_id table (in two parts as first patch only used it for
     MODULE_DEVICE_TABLE.)
 * adt7316-spi
   - of_device_id table
 * adxl372
   - YAML DT binding conversion.
   - Cleanup use of buffer callback functions (precursor to core rework).

   - Simplify getting the i2c adapter from the client.
 * dht11
   - Mote to newer GPIO consumer interface.
 * kxcjk-1013.c
   - Add binding for sensor in display of some ultrabooks after userspace
     tools updated for it not be a problem to report two similar sensors.
 * imx7d
   - drop unused variables.
   - white space
   - define instead of variable for clock frequency that is fixed.
   - drop pointless error message.
 * messon_saradc
   - SPDX
 * sps30
   - MAINTAINERS entry
   - YAML binding conversion.

     part of a long running effort to simplify the core code.
 * stm32-dfsdm:
   - Manage the resolution cleanly in triggerd modes.
   - Add fast mode support which allows more flexible filter choices.
   - Add a comment on the reason for a 16 bit record when technically
     not 'required'.
 * st_lsm6dsx
   - Embed device name in the sensor_settings struct as i3c doesn't
     have a convenient name field to use for this.
 * xilinx-adc
   - Relax constraints on supported platforms to reflect that this
     can used with FPGAs on PCIe cards and hence many architectures.

 Fixes
 * tools
   - fix incorrect handling of 32 bit channels.
 * sca3000
   - Potential endian bug that is unlikely to bite anyone (be64 host
     seems unlikely for this old part).
 * stm32-adc
   - Add vdda-supply. On some boards it needs to be turned on to supply
     the ADC.  DT bindings included.
 * stm32-dfsdm
   - Fix output resolution to work with filter orders other than 3.
   - Fix output datatype as it's signed and previously claimed not to be.

10dd571c66 iio: adis162xx: fix low-power docs & reports
All current ADIS162XX drivers have incorrect values defined via comments.
Also, when an error is reported the printed value is incorrect.

The functionality itself isn't affected, so it's not a critical issue.

And since the change is trivial, it was included in a single patch that
fixes these in one go. All values were correlated with the ones specified
in the data-sheets.

aabcbfe8db iio: sca3000: Potential endian bug in sca3000_read_event_value()
The problem is that "ret" is an int but we're casting it as
"(unsigned long *)&ret" when we do the for_each_set_bit() loop.  This
will not work on big endian 64 bit systems.

fb1589710e iio: Allow to read mount matrix from ACPI
Currently mount matrix is allowed in Device Tree, though there is
no technical issue to extend it to support ACPI.

Convert the function to use device_property_read_string_array() and
thus allow to read mount matrix from ACPI if available.

Example of use in _DSD method:

  Name (_DSD, Package ()
  {
     ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
     Package ()
     {
        Package () { "mount-matrix", Package() {
                "1", "0",     "0",
                "0", "0.866", "0.5",
                "0", "-0.5",  "0.866",
        } },
     }
  })

At the same time drop the "of" prefix from its name and
convert current users.

No functional change intended.

f38ab20b74 iio: st_accel: use ACPI orientation data
Platform-specific ST accelerometer mount matrix information can be
provided by returning a package of 6 integers from the ACPI _ONT
method. This has been seen on Acer products such as Veriton Z4860G,
Z6860G and A890, which include a ST SMO8840 sensor. We have also
confirmed experimentally that the Windows driver uses such information.

The _ONT data format was explained by a ST vendor contact. However,
strangely enough, the _ONT transformations must be applied after first
applying another mount matrix which we determined experimentally. ST
have not commented on why this is the case, but we imagine that perhaps
earlier devices (before _ONT was introduced) required this translation
and hence it became 'standard.'

Interpret the _ONT data and export the equivalent mount matrix to
userspace.

If no _ONT data is present, no mount matrix is exported.

f6ff49b8a3 iio: accell: mma8452: add vdd/vddio regulator operation support
The accelerometer's power supply could be controllable on some
platforms, such as i.MX6Q-SABRESD board, the mma8451's power supplies
are controlled by a GPIO fixed regulator, need to make sure the
regulators are enabled before any communication with mma8451, this
patch adds vdd/vddio regulator operation support.

7f6232e695 iio: accel: kxcjk1013: Add KIOX010A ACPI Hardware-ID
Various 2-in-1's use KIOX010A and KIOX020A as HIDs for 2 KXCJ91008
accelerometers. The KIOX010A HID is for the one in the base and the
KIOX020A for the accelerometer in the keyboard.

Since userspace does not have a way yet to deal with (or ignore) the
accelerometer in the keyboard, this commit just adds the KIOX010A HID
for now so that display rotation will work.

0145b50566 iio/hid-sensors: Fix IIO_CHAN_INFO_RAW returning wrong values for signed numbers
Before this commit sensor_hub_input_attr_get_raw_value() failed to take
the signedness of 16 and 8 bit values into account, returning e.g.
65436 instead of -100 for the z-axis reading of an accelerometer.

This commit adds a new is_signed parameter to the function and makes all
callers pass the appropriate value for this.

While at it, this commit also fixes up some neighboring lines where
statements were needlessly split over 2 lines to improve readability.

d9e8fd0421 iio: adxl372: Refactor the driver
This patch restructures the existing adxl372 driver by adding a module for
SPI and a header file, while the baseline module deals with the chip-logic.

This is a necessary step, as this driver should support in the future
a similar device which differs only in the type of interface used (I2C
instead of SPI).
