Greg Kroah-Hartman 9c15db92a8 1st set of IIO/counter device support, features and cleanup in the 5.13 cycle
Big set in here from Alexandru Ardelean enabling multiple buffer support.
 This includes providing a new directory per buffer that combines
 what was previously in buffer/ and scan_elements/. Old interfaces still
 in place for compatiblity.
 
 Note immuatable branch for scmi patches to allow for some significant
 rework going on in that subsystem.  Merge required updating to reflect
 some changes in IIO.
 
 Late rebase to fix some wrong fixes tags due to some earlier rebases
 made necessary by messing up the immutable branch.
 
 IIO New Device Support
 * adi,ad5686
   - Add info to support AD5673R and AD5677R
 * bosch,bmi088
   - New driver supporting this accelerometer + gyroscope
 * cros_ec_mkbp
   - New driver for this proximity sensor that exposes a 'front'
     sensor. Very simple switch like device, but driver allows it
     to share interface with more sophisticated proximity sensors.
 * iio_scmi
   - New driver to support ARM SCMI protocol to expose underlying
     accelerometers and gyroscopes via this firmware interface.
 * st,st_magn
   - Add ID for IISMDC magnetometer.
 * ti,ads131e0
   - New driver supporting ads131e04, ads131e06 and ads131e08 24 bit ADCs
 
 Counter New Device Support
 * IRQ or GPIO based counter
   - New driver for a conceptually simple counter that uses interrupts
     to perform the count.
 
 Features
 * core
   - Dual buffer supprt including:
      Various helpers to centralize handling of bufferer related elements.
      Document existing and new IOCTLs
      Register the IIO chrdev only if it can actually be used for anything.
      Rework attribute group creation in the core (lots of patches)
      Merge buffer/ and scan_elements/ entries into one list + maintain
      backwards compatible set.
      Introduce the internal logic and IOCTL to allow multiple buffers
      + access to an anon FD per buffer to actually read from it.
      Tidy up tools/iio/iio_generic_buffer and switch to new interfaces.
      Update ABI docs.
      A few follow up fixes, unsuprising as this was a huge bit of rework.
   - Move common case setting of trig->parent to the core.
   - Provide an iio_read_channel_processed_scale() to avoid loss of
     precision from iio_read_channel_processed() then applying integer
     scale. Use it in ntc_thermistor driver in hwmon.
   - Allow drivers to specify labels from elsewhere than DT. Use it for
     bmc150 and kxcjk-1013 labels related to position on 2 in one tablets.
   - Document label usage for proximity and accelerometer sensors.
   - Some local variable renames for consistency
 tools
   - Add -a parameter to iio_event_monitor to allow autoenabling of events.
 * acpi_als
   - Add trigger support for devices that don't support notification method.
 * adi,ad7124
   - Allow more than 8 channels.  This is a complex little device, but is
     capable of supporting up to 16 channels if the share certain
     configuration settings.
 * hrtimer-trigger
   - Support sampling frequency below 1Hz.
 * mediatek,mt8195-auxadc
   - Add compatible to binding docs (always also includes mt8173)
 * st,stm32-adc
   - Enable timetamps when not using DMA.
 * vishay,vcnl3020
   - Sampling frequency control.
 
 Cleanup and minor fixes:
 * treewide
   - Use some getter and setter functions instead of opencoding.
   - Set of fixes for pointless casts in various drivers.
   - Avoid wrong kernel-doc marking on comment blocks.
   - Fix various other minor kernel-doc issues shown by W=1
 * core
   - Use a signed temporary for IIO_VAL_FRACTIONAL_LOG2 to avoid odd casts.
   - Fix IIO_VAL_FRACTIONAL_LOG2 for values between -1.0 and 0.0
   - Add unit tests for iio_format_value()
 * docs
   - Fix formatting/typos in iio_configfs.rst and buffers.rst
   - Add documentation of index in buffers.rst
   - Fix scan element description
   - Avoid some issues with HTML generation from ABI docs by moving
     duplicated defintions to more generic files.
   - Drop reference to long dead mailing list.
 * 104-quad
   - Remove left over deprecated IIO counter ABI.
 * adi,adi-axi-adc
   - Fix wrong bit of docs.
 * adi,ad5791
   - Typos
 * adi,ad9834
    - Switch to device managed functions in probe.
 * adi,adis*
   - Add and use helpers for locking to reduced duplication.
 * adi,adis16480
   - Fix calculation of sampling frequency when using pulse per second input.
 * adi,adis16475
   - Calculate the IMU scaled internal sampling rate and runtime depending
     on sysfs based configuration rather than getting from DT. Drop now
     unnecessary property from DT bindings doc.
 * cros_ec
    - Fix result of a series of recent changes that means extended buffer
      attributes turn up in the wrong place. Too complex to revert the
      various patches unfortunately so this is a bit messy.
 * fsl,mma3452
   - Indentation cleanup.
 * hid-sensors
   - Size of storage needs to increase for some parts when using quaternions.
   - Move the get sensistivity attribute to hid-sensors-common to reduce
     duplication.  Enable it for more device types.
   - Correctly handle relative sensitivity if reported that way including
     documenting the new ABI.
 * maxim,max517
   - Use device managed functions in probe.
 * mediatek,mt6360-adc
   - Use asm/unaligned.h instead of directly including
     unaligned/be_byteshift.h
 * novuton,npcm-adc
   - Local lock instead of missusing mlock.
 * semtech,sx9500
   - Typos
 * st,sensor
   - typo fix
 * st,spear-adc
   - Local lock instead of missusing mlock.
 * st,stm32-adc
   - Long standing HAS_IOMEM dependency fix.
 * st,stm32-counter
   - Remove left over deprecated IIO counter ABI.
