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