Greg Kroah-Hartman 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.
 * adis library
   - 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).
 * bh1710
   - 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.
 * st_accel
   - Tidy up ordering in various buffer related callbacks. This is
     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.
 * counters/ftm-quaddec
   - Fix some formatting io MODULE_AUTHOR
   - MAINTAINERS entry
 
 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.

tristate "Industrial I/O support"
help
The industrial I/O subsystem provides a unified framework for
drivers for many different types of embedded sensors using a
number of different physical interfaces (i2c, spi, etc).
if IIO
config IIO_BUFFER
bool "Enable buffer support within IIO"
help
Provide core support for various buffer based data
acquisition methods.
if IIO_BUFFER
source "drivers/iio/buffer/Kconfig"

config IIO_CONFIGFS
tristate "Enable IIO configuration via configfs"
select CONFIGFS_FS
help
This allows configuring various IIO bits through configfs
(e.g. software triggers). For more info see
Documentation/iio/iio_configfs.rst.
config IIO_TRIGGER
bool "Enable triggered sampling support"
help
Provides IIO core support for triggers. Currently these
are used to initialize capture of samples to push into
buffers. The triggers are effectively a 'capture
data now' interrupt.
config IIO_CONSUMERS_PER_TRIGGER
int "Maximum number of consumers per trigger"
depends on IIO_TRIGGER
default "2"
help
This value controls the maximum number of consumers that a
given trigger may handle. Default is 2.
config IIO_SW_DEVICE
tristate "Enable software IIO device support"
select IIO_CONFIGFS
help
Provides IIO core support for software devices. A software
device can be created via configfs or directly by a driver
using the API provided.
config IIO_SW_TRIGGER
tristate "Enable software triggers support"
select IIO_CONFIGFS
help
Provides IIO core support for software triggers. A software
trigger can be created via configfs or directly by a driver
using the API provided.
config IIO_TRIGGERED_EVENT
