42Description:	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.
54
55		The files are write only.

71		auxiliary outage or power refresh, ASIC thermal shutdown, halt,
72		hotswap, watchdog, firmware reset, long press power button,
73		short press power button, software reset. Value 1 in file means
74		this is reset cause, 0 - otherwise. Only one of the above
75		causes could be 1 at the same time, representing only last
76		reset cause.
