Currently, mlxsw supports a single hwmon device and registers it with attributes corresponding to the various objects found on the main board such as fans and gearboxes. Line cards can have the same objects, but unlike the main board they can be added and removed while the system is running. The various hwmon objects found on these line cards should be created when the line card becomes available and destroyed when the line card becomes unavailable. The above can be achieved by representing each line card as a different hwmon device and registering / unregistering it when the line card becomes available / unavailable. Prepare for multi hwmon device support by splitting 'struct mlxsw_hwmon' into 'struct mlxsw_hwmon' and 'struct mlxsw_hwmon_dev'. The first will hold information relevant to all hwmon devices, whereas the second will hold per-hwmon device information.

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.
