[PATCH net 0/3] net: mvpp2: Fix hangs when starting some interfaces on 7k/8k

[Maxime Chevallier <maxime.chevallier@bootlin.com>]

Armada 7K / 8K clock management has recently been reworked, see :

commit c7e92def1ef4 ("clk: mvebu: cp110: Fix clock tree representation")

I have been experiencing overall system hangs on MacchiatoBin when starting
the eth1 interface since then. It turns out some clocks dependencies were
missing in the PPv2 and xmdio driver, the clock rework made this visible.

This series adds the missing clocks in the CP-110 DT bindings for these 2
controllers, updating the documentation accordingly. It also adds support
for the missing 'MG Core clock' in mvpp2.

Thanks to Gregory Clement for finding the root cause of this bug.
