Pali Rohár 1fe976d308 net: phy: marvell: fix detection of PHY on Topaz switches
Since commit fee2d54641 ("net: phy: marvell: mv88e6390 temperature
sensor reading"), Linux reports the temperature of Topaz hwmon as
constant -75°C.

This is because switches from the Topaz family (88E6141 / 88E6341) have
the address of the temperature sensor register different from Peridot.

This address is instead compatible with 88E1510 PHYs, as was used for
Topaz before the above mentioned commit.

Create a new mapping table between switch family and PHY ID for families
which don't have a model number. And define PHY IDs for Topaz and Peridot
families.

Create a new PHY ID and a new PHY driver for Topaz's internal PHY.
The only difference from Peridot's PHY driver is the HWMON probing
method.

Prior this change Topaz's internal PHY is detected by kernel as:

  PHY [...] driver [Marvell 88E6390] (irq=63)

And afterwards as:

  PHY [...] driver [Marvell 88E6341 Family] (irq=63)

README

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.
