[PATCH net-next v2 0/2] mv88e6xxx: SERDES on mv88e6321 letter

[Fidan Aliyeva <fidan.aliyeva.ext@ericsson.com>]

This patch series add code support to be able to use SERDES feature of
mv88e6321 version of Marvel mv88e6xxx series. mv88e6321 has 2 ports to
support high speed SERDES but the support is lacking in the driver.

mv88e6321 version has a similar architecture to mv88e6352 version making it
possible to reuse its pcs functions. That's why the patch series consist of
2 parts:
1. Refactor the serdes functions and pcs_init of mv88e6352 to be more
generic
2. Add the SERDES support for mv88e6321 reusing 6352's pcs functions

The final code has been built on top of net-next tree and tested on
mv88e6321 ethernet device directly by ip ping tests, performance tests and
also verifying the switch's expected register values.

Referred document: 88E6321/88E6320 Functional Specification

Code has been built with allmodconfig and allyesconfig. checkpatch.pl was
also run
