Greg Kroah-Hartman ebc8f4f603 Second set of IIO + counter new device support, features etc for the 5.5 cycle.
Note two merge commits in here, both for immutable branches based
 of 5.4-rc1.
 1. Ti eqep driver because of some file moves in precursor patches.
    I suspect no one else will pull this one.
 2. ab8500 refactor as changes in power supply, hwmon and mfd trees.
    This may come via numerous trees as well as IIO.
 
 Counter subsystem related
 * ti eqep
   - New device support with bindings.
   - Includes prior file move to reflect more general use of ti-pwmss.
 * Counter core
   - simplify count_read and count_write callbacks + document change.
   - fix a typo in docs.
 
 Various subsystems related
 * AB8500
   - ab8500_btemp driver converted to be an IIO consumer driver.
   - ab8500_charger driver converted to be an IIO consumer driver.
   - ab8500_fg fuel gauge driver converted to be an IIO consumer driver.
   - ab8500 hwmon driver converted to be an IIO consumer driver.

   - new driver for this multi-sensor type temperature interface.
     Includes complex DT bindings.
 * max1027
   - support for 12 bit devices, max1227, max1229 and max1231 + add to trivial
     bindings.
 * st_lsm6dsx
   - support for the LSM6DS0 6 axis MEMs sensor.
     Note different from the LSM6DSO which the driver already supports *sigh*

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
