At the moment, our driver relies on 'wacom_battery_get_property()' to determine the most likely battery state (e.g charging, discharging, or full) based on the information available. It is not always possible for the function to properly determine this, however. For instance, whenever an AES pen leaves proximity the battery state becomes indeterminite. This commit adds the ability to provide it with explict state information if desired. Whenever explicit state is not required (the majority of circumstances), WACOM_POWER_SUPPLY_STATUS_AUTO can be used in its place. Three uses of explicit battery status are added: two wireless disconnect paths and the AES case mentioned above.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
