[GIT PULL] ARM: mvebu: dt for v4.11 (#3)

[Gregory CLEMENT]

Hi,

Here is the third pull request for dt for mvebu for v4.11.

As for the soc, I hope it is not too late, the support for this new
SoC needed to have several iteration and the last one was mainly
cosmetic. The code was in linux-next since last week by the way. So I
don't expect any regression with it.

Pulled into next/dt, nice to see this getting added! Just for my information,
do we also support the actual switch driver in Linux, or just the parts that
are common with Armada?

Currently it is only the common parts with Armada XP. Adding switches
support seems a big task, see the answer of Chris Packham about it:
http://lists.infradead.org/pipermail/linux-arm-kernel/2017-January/476910.html

And also the switch of this family seems different of the one having
support in the dsa subsystem:

Thanks,

Gregory

Hi Arnd

This just supports the SoC part of the switch. As Gregory pointed out,
this switch is a completely different beast to the Marvell SOHO
switches DSA supports.
