There is difference in implementation of per_out pins between KSZ9563 and LAN937x. In KSZ9563, Timestamping control register (0x052C) bit 6, if 1 - timestamp input and 0 - trigger output. But it is opposite for LAN937x 1 - trigger output and 0 - timestamp input. As per per_out gpio pins, KSZ9563 has four Led pins and two dedicated gpio pins. But in LAN937x dedicated gpio pins are removed instead there are up to 10 LED pins out of which LED_0 and LED_1 can be mapped to PTP tou 0, 1 or 2. This patch sets the bit 6 in 0x052C register and configure the LED override and source register for LAN937x series of switches alone.

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.
