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.
