[ Upstream commit 9780f535f8e0f20b4632b5a173ead71aa8f095d2 ]
To initialize the taprio block in lan966x, it is required to configure
the register REVISIT_DLY. The purpose of this register is to set the
delay before revisit the next gate and the value of this register depends
on the system clock. The problem is that the we calculated wrong the value
of the system clock period in picoseconds. The actual system clock is
~165.617754MHZ and this correspond to a period of 6038 pico seconds and
not 15125 as currently set.
Fixes: e462b27173 ("net: lan966x: Add offload support for taprio")

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.
