63Description: These files allow asserting system power cycling, switching
64 power supply units on and off and system's main power domain
65 shutdown.
66 Expected behavior:
67 When pwr_cycle is written 1: auxiliary power domain will go
68 down and after short period (about 1 second) up.
69 When psu1_on or psu2_on is written 1, related unit will be
70 disconnected from the power source, when written 0 - connected.
71 If both are written 1 - power supplies main power domain will
72 go down.
73 When pwr_down is written 1, system's main power domain will go
74 down.

76 The files are write only.
