The bindings have been updated to support two clocks, but the
original clock now requires the name fck.  Add a clock-names
list in the device tree with fck in it.

Hi Adam

I think requires is too strong. As far as i can see, you don't
introduce a change using the name 'fck'. So the name is optional,
which is good, because otherwise you would break backwards
compatibility with DT blobs.

Is the plan to merge this whole patchset via netdev? If so, you need
to repost anyway, once netdev reopens. So maybe you can change the
wording?

The DTS patches should go in through the renesas and soc trees.
I can apply them as soon as the DT binding patch has been accepted.

Thanks!
