This is a prerequisite for transitioning the m_can driver to rx-offload, which works best with TX and RX timestamps. The timestamps provided by M_CAN are 16-bit, timed according to the nominal bit timing, and may be prescaled by a multiplier up to 16. We choose the highest prescalar so that the timestamp wraps every 2^20 bit times, or 209 ms at a bus speed of 5 Mbit/s. Timestamps will have a precision of 16 bit times.

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.
