Before configuring the NIX block, the AF driver initiates the
"NIX block X2P bus calibration" and verifies that NIX interfaces
such as CGX and LBK are active and functioning correctly.
On few silicon variants(CNF10KA and CNF10KB), X2P calibration failures
have been observed on some CGX blocks that are not mapped to the NIX block.
Since both NIX-mapped and non-NIX-mapped CGX blocks share the same
VENDOR,DEVICE,SUBSYS_DEVID, it's not possible to skip probe based on
these parameters.
This patch introuduces "is_cgx_mapped_to_nix" API to detect and skip
probe of non NIX mapped CGX blocks.

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.
