Apple currently supports three very common USB chargers: https://www.apple.com/power-adapters/ These chargers implement a proprietary Apple method for advertising 1A, 2.1A, and 2.4A at 5V called "Brick ID". In addition, 3rd parties implement the same charging method in many charging accessories that work with iOS devices. Devices that have charger detection chips such as the Pericom PI3USB9281, eg. Google Chromebook Pixel 2015, are capable of detecting these chargers, so let's add a type to facilicate passing that info up to userspace. This adds a separate power supply type for Apple's proprietary "Brick ID" charging method.

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.
