+description: |
+ Central resources are controlled by a set of software-locked registers,
+ which can be used to prevent accidental accesses. Syscon generates
+ the various bus and peripheral clocks and controls the system startup
+ configuration.
+
+ The System Controller (Syscon) provides:
+ - Clock control
+ - Power management
+ - System configuration management
+
+ Syscon registers are common for all EP93xx SoC's, through some actual peripheral
+ may be missing depending on actual SoC model.
