Actually I was wrong with my assumption that there was no dependency.
For the binding documentation there is dependecy accross the series I
sent.

This patch depends on "pinctrl: dt-bindings: add documentation for AP806
pin controllers" [1] and "pinctrl: dt-bindings: add documentation for
CP110 pin controllers" [3] from the series "Add support for the pin
controllers on the Marvell Armada 7K/8K".

As you are maintainer of both gpio and pinctrl subsystem it will be easy
to resolv.

But these last patches depend also on "clk: mvebu: ap806: introduce a
new binding" [3] in the clock series "Improve ap806 clk support on
Marvell Armada 7K/8K" and on "clk: mvebu: cp110: introduce a new
binding" [4] in the clock series "Improve cp110 clk support on Marvell
Armada 7K/8K".

So for these particular patches, either I rebase them on the v4.12-rc2
and there will be a small merge conflict during the merge window for
v4.13, or we can ask a stable branch with only these few patches (I am
adding the clock maintainer to this email).

If we chose this last option I can split the clock patches to have patch
modifying only the binding documentation.

Gregory
