Most flexcan IP cores support 2 RX modes: - FIFO - mailbox Some IP core versions cannot receive CAN RTR messages via mailboxes. This patch adds quirks to document this. This information will be used in a later patch to switch from FIFO to more performant mailbox mode at the expense of losing the ability to receive RTR messages. This trade off is beneficial in certain use cases. Link: https://lore.kernel.org/all/20220107193105.1699523-5-mkl@pengutronix.de Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
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.
