Currently REG_NAC (nominal available capacity) is mapped to power-supply's CHARGE_NOW property. Some chips do not have REG_NAC and do not expose CHARGE_NOW at the moment. Some bq27xxx chips also have another register REG_RM (remaining capacity). The difference between REG_NAC and REG_RM is load compensation. This patch adds register information for REG_RM for all supported fuel gauges. On systems having REG_NAC it is ignored, so behaviour does not change. On systems without REG_NAC, REG_RM will be used to provide CHARGE_NOW functionality. As a result there are three more chips exposing CHARGE_NOW: bq27z561, bq28z610 and bq34z100 Signed-off-by: Hermes Zhang <chenhuiz@axis.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>
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.
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.
