LI Qingwu 4eed7f5a83 power: supply: bq27xxx: Add support for BQ78Z100 
Add support for TI BQ78Z100, I2C interface gas gauge.
It provides a fully integrated safety protection
and authentication for 1 to 2-series cell Li-Ion and
Li-Polymer battery packs.

The patch was tested with BQ78Z100 equipment.

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.
