An ina3221 chip has three input ports. Each port is used to measure the voltage and current of its input source. The DT binding now has defined bindings for their input sources, so the driver should read these information and handle accordingly. This patch adds a new structure of input source specific information including input source label, shunt resistor value and its connection status. It exposes these labels via in[123]_label sysfs nodes upon available, and also disables those channels where there are no input source being connected. Meanwhile, it also adds in[123]_enable sysfs nodes for users to get control of three channels, and returns -ENODATA code for any sensor read according to hwmon ABI.

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.
