|
|
This node defines the System Control Unit of the EN7523 SoC,
|
|
a collection of registers configuring many different aspects of the SoC.
|
|
|
|
The clock driver uses it to read and configure settings of the
|
|
PLL controller, which provides clocks for the CPU, the bus and
|
|
other SoC internal peripherals.
|
|
|
|
Each clock is assigned an identifier and client nodes use this identifier
|
|
to specify which clock they consume.
|
|
|
|
All these identifiers can be found in:
|
|
[1]: <include/dt-bindings/clock/en7523-clk.h>.
|
|
|
|
The clocks are provided inside a system controller node.
