The ROHM BD79703 is a 6 channel digital to analog converter. Based on the data-sheet examples the hardware would support setting the DAC word without changing the actual output. The data-sheet is not too specific on how the enabling the output of new voltage set by DAC should be done - hence this is not implemented by the driver. The BD79703 would also support two specific "PULL_DOWN" modes. These aren't currently supported by the driver either. Add a very basic support for controlling the channel outputs one-by-one.

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.
