Jonathan Bakker 754718a5b4 iio: adc: Add scaling support to exynos adc driver
Currently the driver only exposes the raw counts.  As we
have the regulator voltage and the maximum value (stored in
the data mask), we can trivially produce a scaling fraction
of voltage / max value.

This assumes that the regulator voltage is in fact the max
voltage, which appears to be the case for all mainline dts
and cross referenced with the public Exynos4412 and S5PV210
datasheets.

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.
