This patch adds basic support for Analog Devices I2C programmable linear battery charger. With this driver, some parameters can be read and configured such as: * trickle charge current level (PRECHARGE_CURRENT) * trickle charge voltage threshold (VOLTAGE_MIN) * weak charge threshold (VOLTAGE_AVG) * constant current (CONSTANT_CHARGE_CURRENT) * constant charge voltage limit (CONSTANT_CHARGE_VOLTAGE_MAX) * battery full (CAPACITY_LEVEL) * input current limit (INPUT_CURRENT_LIMIT) * charger status (STATUS) * battery status (CAPACITY_LEVEL) * termination current (CHARGE_TERM_CURRENT) Datasheet: http://www.analog.com/media/en/technical-documentation/data-sheets/ADP5061.pdf Signed-off-by: Stefan Popa <stefan.popa@analog.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
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.
