This commit adds the internal functions to control the Toshiba laptop. Unlike for example ThinkPads where this control is granular here it is just off/on. When off it charges to 100%. When on it charges to about 80%. Controlling this setting is done via HCI register 0x00ba. Setting to value 1 will result in limiting the charing to 80% of the battery capacity, while setting it to 0 will allow charging to 100%. Reading the current state is a bit weird, and needs a 1 set in the last position of the query for whatever reason. In addition, the read may return 0x8d20 (Data not available) rarely, so a retry mechanism is needed. According to the Windows program used to control the feature the setting will not take effect until the battery has been discharged to around 50%. However, in my testing it takes effect as soon as the charge drops below 80%. On Windows Toshiba branded this feature as "Eco charging".

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.
