| 42 | Description: These files allow asserting system power cycling, switching |
| 43 | power supply units on and off and system's main power domain |
| 44 | shutdown. |
| 45 | Expected behavior: |
| 46 | When pwr_cycle is written 1: auxiliary power domain will go |
| 47 | down and after short period (about 1 second) up. |
| 48 | When psu1_on or psu2_on is written 1, related unit will be |
| 49 | disconnected from the power source, when written 0 - connected. |
| 50 | If both are written 1 - power supplies main power domain will |
| 51 | go down. |
| 52 | When pwr_down is written 1, system's main power domain will go |
| 53 | down. |
