The Intel Cherry Trail Whiskey Cove PMIC does not contain a builtin battery charger, instead boards with this PMIC use an external TI bq24292i charger IC, which is connected to a SMBUS controller built into the PMIC. This commit adds an i2c-bus driver for the PMIC's builtin SMBUS controller. The probe function for this i2c-bus will also register an i2c-client for the TI bq24292i charger after the i2c-bus has been registered. Note that several device-properties are set on the client-device to tell the bq24190 power-supply driver to integrate the Whiskey Cove PMIC and e.g. use the PMIC's BC1.2 detection (through extcon) to determine the maximum input current.

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.
