[PATCH net-next 00/27] net: mvpp2: add basic support for PPv2.2

[Thomas Petazzoni]

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.

Here is a quick overview of the series:

 - Patch 1 updates the Device Tree binding documentation.

 - Patch 2 to 10 make improvements to the mvpp2 not directly related
   to the PPv2.2 support, but useful to have as they cleanup some dead
   code, fix a few issues, etc.

 - Patch 11 switches the driver to build_skb(), which is needed to
   support PPv2.2 (details in the commit log itself)

 - Patch 12 makes the driver build on 64 bits platform.

 - Patches 13 to 26 add the PPv2.2 support step by step.

 - Patch 27 finally adds the compatible string, which makes the PPv2.2
   support usable.

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!

Best regards,

Thomas
