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.
