Marc Kleine-Budde <mkl@pengutronix.de> says: This series first introduces the can_state_get_by_berr_counter() helper function. It returns the current TX and RX state depending on the provided CAN bit error counters. It will be later used by the at91_can driver. The remaining patches of this series first clean up the at91_can driver, clean up the bus- and line error (including bus-off) handling, and then convert it use the rx_offload helper. The driver works better under high system load and the order of received CAN frames is better maintained. Due to a hardware limitation the converted driver could trigger a race condition in the can_restart() CAN bus-off handler. The patch series [1] fixes the issue.

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.
