Support voltage control for regulators on ROHM BD71815 PMIC. ROHM BD71815 contains 5 bucks, 7 LDOs and a boost (intended for LED). Bucks 1 and 2 support HW state based voltage level and enable states. Other regulators support HW state based enable states. All bucks and LDOs 1-5 allow voltage changes for RUN state and LDO4 can be enabled/disabled via GPIO. LDO3 does support changing between two predetermined voltages by using a GPIO but this functionality is not included in this commit. This work is derived from driver originally written by Tony Luo <luofc@embedinfo.com> - although not much of original work is left.

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.
