Not several, just two types of nodes.
One is clockgen node, the other is PLL and mux nodes.
The reason they lumped together is that the clockgen node is not only IP block
Node but also a clock provider node.
At first, I want to add a extra fixed-clock node and move the clock-frequency of clockgen
Node to it, but it is against the backward compatibility which I think it is not a big deal,
Because nobody hasn't used it yet.
If I add a extra node with the clock-frequency property and don't move the
clock-frequency property of clockgen, that would be redundant because both clockgen node
and the extra node have the same clock-frequency node.
So, I choose what I did now.
Could you give me some suggestions on this?
