Wangxun 10Gb ethernet chip is connected to Designware I2C, to communicate with SFP. Introduce the property "wx,i2c-snps-model" to match device data for Wangxun in software node case. Since IO resource was mapped on the ethernet driver, add a model quirk to get regmap from parent device. The exists IP limitations are dealt as workarounds: - IP does not support interrupt mode, it works on polling mode. - Additionally set FIFO depth address the chip issue.

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.
