Robert Marko d1cb613efb net: phy: qcom: add support for QCA807x PHY Family
This adds driver for the Qualcomm QCA8072 and QCA8075 PHY-s.

They are 2 or 5 port IEEE 802.3 clause 22 compliant 10BASE-Te,
100BASE-TX and 1000BASE-T PHY-s.

They feature 2 SerDes, one for PSGMII or QSGMII connection with
MAC, while second one is SGMII for connection to MAC or fiber.

Both models have a combo port that supports 1000BASE-X and
100BASE-FX fiber.

PHY package can be configured in 3 mode following this table:

              First Serdes mode       Second Serdes mode
Option 1      PSGMII for copper       Disabled
              ports 0-4
Option 2      PSGMII for copper       1000BASE-X / 100BASE-FX
              ports 0-4
Option 3      QSGMII for copper       SGMII for
              ports 0-3               copper port 4

Each PHY inside of QCA807x series has 4 digitally controlled
output only pins that natively drive LED-s.
But some vendors used these to driver generic LED-s controlled
by userspace, so lets enable registering each PHY as GPIO
controller and add driver for it.

These are commonly used in Qualcomm IPQ40xx, IPQ60xx and IPQ807x
boards.

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.
