ERR051586: Compliance with 8GT/s Receiver Impedance ECN. The default value of GEN3_RELATED_OFF[GEN3_ZRXDC_NONCOMPL] is 1 which makes receiver non-compliant with the ZRX-DC parameter for 2.5 GT/s when operating at 8 GT/s or higher. It causes unnecessary timeout in L1. So the workaround is to set GEN3_RELATED_OFF[GEN3_ZRXDC_NONCOMPL] to 0. Add this workaround in the dw_pcie_host_ops::post_init() callback for i.MX95 platforms.

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 reStructuredText 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.
