Subject: [PATCHv2 net-next 00/16] net: mvpp2: add basic support for PPv2.2

Hello,

The goal of this patch series is to add basic support for PPv2.2 in
the existing mvpp2 driver. mvpp2 currently supported the PPv2.1
version of the IP, used in the 32 bits Marvell Armada 375 SoC. PPv2.2
is an evolution of this IP block, used in the 64 bits Marvell Armada
7K/8K SoCs.

In order to ease the review, the introduction of PPv2.2 support has
been made into multiple small commits, with the final commit adding
the compatible string that makes the PPv2.2 support actually
usable. The series remain fully bisectable.

This series depends on the series named "net: mvpp2: misc improvements
and preparation patches".

I'd like to thank Stefan Chulski and Marcin Wojtas, who helped me a
lot in the development of this patch series, by reviewing the patches,
and giving lots of useful hints to debug the driver on PPv2.2. Thanks!

Changes since v1:

 - Made a separate series from the set of patches doing preparation
   changes/fixes to the mvpp2 driver.

 - Rebased on top of v4.10-rc1.

 - Update Kconfig text of the mvpp2 driver to mention the support for
   Armada 7K and 8K (PPv2.2).

Best regards,

Thomas
