Antoni Pokusinski 2aac3f9aec iio: humidity: si7020: add heater support
This patch adds support for the integrated on-chip heater that is present
on all the devices supported by this driver (si7020, si7021, si7013, th6).
In order to configure the heater, the driver interacts with the following
device registers:
* User Register - the 2nd bit of this register is a "Heater Enable bit"
  (0 means that the heater is off, 1 means that it's on).
* Heater Register - this register is present only on the si70xx devices
  and controls the current flowing through the heater. The 4 lower bits
  of this register can be assigned values from 0x0 to 0xF.

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 reStructuredText 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.
