   3 Power Reset and Clock Manager lists the device clocks and clockdomains under
   4 a DT hierarchy. Each TI SoC can have multiple PRCM entities listed for it,
   5 each describing one module and the clock hierarchy under it. see [1] for
   6 documentation about the individual clock/clockdomain nodes.
