Second set of Counter and IIO new device support, cleanups etc for 5.14

Browse Source 
Counter
 ------
 
 First part of general rework of counter subsystem to add a chrdev interface
 for event drive data capture.  Most of it will hopefully land next cycle.
 
 * Consolidate documentation to avoid multiple copies of same docs in per
   device files.
 * Constify various arrays etc across subsystem.
 * 104-quad-8:
   - Annotate the module config parameter to avoid using it when kernel is
     locked down.
   - Spelling and trivial comment drops etc
 * Intel QEP
   - Follow up cleanups of trivial stuff from initial patch series.
 
 IIO
 ---
 
 Includes some cleanups as part of two ongoing audits
 - runtime pm usage in IIO.
 - Insufficient alignment on buffers passed to
 iio_push_to_buffers_with_timstamp()
 
 New device support
 * bosch,bmc150
   - Add ID for BMA253
 
 Minor features / cleanups / minor fixes / late breaking fixes
 * iio_push_to_buffers_with_timestamp() alignment fixes.
   This set includes those where the best option is to mark the buffer as
   __aligned(8). Normally this choice was made because there is too high a degree
   of possible variation in number of channels enabled to be able to guarantee
   the timestamp was always in the same location.  This ruled out the more
   obvious structure form used in other drivers. Only one small class of
   related issues have patches under review and we can finally tighten up the
   explicit rules to reflect the hidden requirement.
 
 * dummy
   - Kconfig build dependency fix.
 * adi,ad_sigma_delta
   - General devm related simplifications for these devices.
 * adi,adf4350
   - Fix some missing cleanup on error path.
 * adi,adis, ADC drivers.
   - Clean out unneeded spi_set_drvdata()
 * ams-taos,tcs3472
   - Fix a potential free of an irq that was never allocated.
 * atlas,sensor
   - Drop unbalanced runtime pm call and use pm_runtime_resume_and_get()
     to reduce boilerplate.
 * bosch,bma180
   - Fix bandwidth register values used.
 * bosch,bmc150
   - Fix wrong pointer being dereferenced in remove.
   - Stop device trying unregister itself rather than the second device.
   - Refactor ACPI second device handing.
   - Add support for DUAL250E ACPI HID.
   - Move some stuff into the header to enable following patches to not
     add additional accessor functions. Drop existing accessors.
   - Add support for hinge angle setting with DUAL250E ACPI DSM to ensure
     keyboard and touchpad enabled correctly when in laptop mode and disabled
     otherwise.
   - Add label attr for the multiple sensor locations with DUAL250E ACPI HID.
   - Fix scale units for bma222
   - Various reordering of devices supported lists to be alphabetical order.
   - Drop unnecessary duplicated chip_info_tbl[] entries.
   - Document that some devices have two interrupts, even if not currently
     used by the driver.
   - Move bma254 over to the bma255 driver.
   - Move to more consistent scale values, based on assumption that some
     datasheets use lower precision in their calculations in comparison
     with others.
 * hid-sensors
   - Use namespaces for exported symbols.
   - Update includes using manual inspection of output of the
     include-what-you-use tool.
 * invensense,icp10100
   - Drop unbalanced runtime pm put. Use pm_runtime_resume_and_get() to cleanly
     handle potential error.

BMA222, BMA222E, BMA250E, BMA253, BMA254, BMA255, BMA280, BMC150, BMI055.
Note that some of these are combo modules:

- BMI055: accelerometer and gyroscope
This is a combo module with both accelerometer and magnetometer.
This driver is only implementing accelerometer part, which has
its own address and register map.

* changed to be used in laptop mode after the power-on / resume.
*
* This DSM takes 2 angles, selected by setting aux0 to 0 or 1, these presumably
* define the angle between the gravity vector measured by the accelerometer in
* the display (aux0=0) resp. the base (aux0=1) and some reference vector.
