Jonathan Lemon says: ==================== Broadcom PTP PHY support This adds PTP support for the Broadcom PHY BCM54210E (and the specific variant BCM54213PE that the rpi-5.15 branch uses). This has only been tested on the RPI CM4, which has one port. There are other Broadcom chips which may benefit from using the same framework here, although with different register sets. ==================== Link: https://lore.kernel.org/r/20220622050454.878052-1-jonathan.lemon@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
