14 This node defines the System Control Unit of the EN7523 SoC,
15 a collection of registers configuring many different aspects of the SoC.
17 The clock driver uses it to read and configure settings of the
18 PLL controller, which provides clocks for the CPU, the bus and
19 other SoC internal peripherals.
21 Each clock is assigned an identifier and client nodes use this identifier
22 to specify which clock they consume.
24 All these identifiers can be found in:
25 [1]: <include/dt-bindings/clock/en7523-clk.h>.
27 The clocks are provided inside a system controller node.
