This just covers the actual PLL and divider clock nodes. In the actual DTs they are somewhat unconnected (no ranges or bus compatible) children of the sregs node, but for the actual clock bindings this is not relevant. One oddity is that the addresses are relative to the parent node, without that being pronounced using a ranges property. But this is too late to fix now.
