+Description: These files allow asserting system power cycling, switching
+ power supply units on and off and system's main power domain
+ shutdown.
+ Expected behavior:
+ When pwr_cycle is written 1: auxiliary power domain will go
+ down and after short period (about 1 second) up.
+ When psu1_on or psu2_on is written 1, related unit will be
+ disconnected from the power source, when written 0 - connected.
+ If both are written 1 - power supplies main power domain will
+ go down.
+ When pwr_down is written 1, system's main power domain will go
+ down.
+
+ The files are write only.
