Hi Sergej,

I abandoned those binding a while back. The reason is that those are
one-node-per-clock bindings, which are unpopular with the DT crowd.
Instead most bindings today use a single node to represent a clock
provider, which maps onto a clock driver in Linux.

Is your clock provider made up of only a single clock? If so then the
bindings you mentioned above may be appropriate. But if you have a clock
controller IP block that manages several clocks then it is better for
you to follow the clock provider binding style. There is no shortage of
good examples on how to do this. See the QCOM, Samsung and Nvidia
bindings for ideas.

Regards,
Mike
