Provide a list of ->available_scan_masks which match the device's capabilities. Basically, these devices are able to scan from 0 to N, N being the highest voltage channel requested by the user. The temperature can be included or not, but cannot be retrieved alone. The consequence is, instead of reading and pushing to the IIO buffers all channels each time, the "minimum" number of channels will be scanned and pushed based on the ->active_scan_mask. For example, if the user wants channels 1, 4 and 5, all channels from 0 to 5 will be scanned and pushed to the IIO buffers. The core will then filter out the unneeded samples based on the ->active_scan_mask that has been selected and only channels 1, 4 and 5 will be available to the user in the shared buffer. Provide a comment in the code explaining this logic.

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.
