When the BQ27xxx driver was originally written the w1 subsystem only allowed device drivers for w1 attached devices to live in the w1 subsystem. Kernel driver subsystems expect that the driver for a device live in the directory of the subsystem for which it implements functionality, not in the directory of the bus that it is attached. To work around this, the BQ27xxx driver was implemented as a platform device driver and the interface driver would instantiate this device from within the w1 directory, then pass a w1 read callback as platform data. As we can now have the w1 interface driver in the power/supply directory (like we do already with the i2c interface driver) we can remove this middle-layer platform driver. Signed-off-by: Andrew F.

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.
