Document the IPQ5018 Internal Gigabit Ethernet PHY found in the IPQ5018 SoC. Its output pins provide an MDI interface to either an external switch in a PHY to PHY link scenario or is directly attached to an RJ45 connector. The PHY supports 10/100/1000 mbps link modes, CDT, auto-negotiation and 802.3az EEE. For operation, the LDO controller found in the IPQ5018 SoC for which there is provision in the mdio-4019 driver. Two common archictures across IPQ5018 boards are: 1. IPQ5018 PHY --> MDI --> RJ45 connector 2. IPQ5018 PHY --> MDI --> External PHY In a phy to phy architecture, the DAC needs to be configured to accommodate for the short cable length. As such, add an optional boolean property so the driver sets preset DAC register values accordingly.

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.
