commit1c51aad847upstream. AXP803/AXP813 have a flag that enables/disables the AC power supply input. This flag does not affect the status bits in PWR_INPUT_STATUS. Its effect can be verified by checking the battery charge/discharge state (bit 2 of PWR_INPUT_STATUS), or by examining the current draw on the AC input. Take this flag into account when getting the ONLINE property of the AC input, on PMICs where this flag is present.

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.
