The can_fixup_bittiming() function is used to validate the user-supplied low-level bit timing parameters and calculate the bitrate prescaler (brp) from the requested time quanta (tq) and the CAN clock of the controller. can_fixup_bittiming() selects the best matching integer bit rate prescaler, which may result in a different time quantum than the value specified by the user. Calculate the resulting time quantum and assign it so that the user sees the effective time quantum.

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.
