Thanks for the changes, but the question what is this remains. Clock
consumers use "clocks" property. Is this a clock controller (provider)
instead?

Best regards,
Krzysztof

Hi Krzysztof,

Yes, this is a clock provider node, I will add the
correct description and will also update the
example with a clock consumer node that is using
a clock from this

That should be enough right?

Thanks for the description. Skip the consumer example please, just
mention shortly what is this. If this is one clock, then node name is
correct. If there are more clocks inside, then the node name should be
"clock-controller".
