On the sam9263 the SR bits for bus off, error passive, warning limit, and error active are not latched and reflect the current status of the controller. On the sam9x5 and newer SoCs these bits are latched. To simplify the code, use can_state_get_by_berr_counter() to get the state of the controller regardless of the SoC version.

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.
