The fusb302 Type-C port-controller cannot control the current-limit directly, so we need to exported the limit so that another driver (e.g. the charger driver) can pick the limit up and configure the system accordingly. The power-supply subsys already provides infrastructure for this, power-supply devices have the notion of being supplied by another power-supply and have properties through which we can export the current-limit. Register a power_supply and export the current-limit through the power_supply's current-max property.

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.
