29	Description
30	-----------
31	
32	This driver supports hardware monitoring for Analog Devices ADM1075, ADM1275,
33	ADM1276, ADM1278, ADM1293, and ADM1294 Hot-Swap Controller and Digital
34	Power Monitors.
35	
36	ADM1075, ADM1275, ADM1276, ADM1278, ADM1293, and ADM1294 are hot-swap
37	controllers that allow a circuit board to be removed from or inserted into
38	a live backplane. They also feature current and voltage readback via an
39	integrated 12 bit analog-to-digital converter (ADC), accessed using a
40	PMBus interface.
41	
42	The driver is a client driver to the core PMBus driver. Please see
43	Documentation/hwmon/pmbus for details on PMBus client drivers.
44	
45	
46	Usage Notes
47	-----------
48	
49	This driver does not auto-detect devices. You will have to instantiate the
50	devices explicitly. Please see Documentation/i2c/instantiating-devices for
51	details.
52	
53	The ADM1075, unlike many other PMBus devices, does not support internal voltage
54	or current scaling. Reported voltages, currents, and power are raw measurements,
55	and will typically have to be scaled.
56	
57	
58	Platform data support
59	---------------------
60	
61	The driver supports standard PMBus driver platform data. Please see
62	Documentation/hwmon/pmbus for details.
63	
64	
65	Sysfs entries
66	-------------
67	
68	The following attributes are supported. Limits are read-write, history reset
69	attributes are write-only, all other attributes are read-only.
70	
71	inX_label		"vin1" or "vout1" depending on chip variant and
72				configuration. On ADM1075, ADM1293, and ADM1294,
73				vout1 reports the voltage on the VAUX pin.
74	inX_input		Measured voltage.
75	inX_min			Minimum Voltage.
76	inX_max			Maximum voltage.
77	inX_min_alarm		Voltage low alarm.
78	inX_max_alarm		Voltage high alarm.
79	inX_highest		Historical maximum voltage.
80	inX_reset_history	Write any value to reset history.
81	
82	curr1_label		"iout1"
83	curr1_input		Measured current.
84	curr1_max		Maximum current.
85	curr1_max_alarm		Current high alarm.
86	curr1_lcrit		Critical minimum current. Depending on the chip
87				configuration, either curr1_lcrit or curr1_crit is
88				supported, but not both.
89	curr1_lcrit_alarm	Critical current low alarm.
90	curr1_crit		Critical maximum current. Depending on the chip
91				configuration, either curr1_lcrit or curr1_crit is
92				supported, but not both.
93	curr1_crit_alarm	Critical current high alarm.
94	curr1_highest		Historical maximum current.
95	curr1_reset_history	Write any value to reset history.
96	
97	power1_label		"pin1"
98	power1_input		Input power.
99	power1_input_lowest	Lowest observed input power. ADM1293 and ADM1294 only.
100	power1_input_highest	Highest observed input power.
101	power1_reset_history	Write any value to reset history.
102	
103				Power attributes are supported on ADM1075, ADM1276,
104				ADM1293, and ADM1294.
105	
106	temp1_input		Chip temperature.
107				Temperature attributes are only available on ADM1278.
108	temp1_max		Maximum chip temperature.
109	temp1_max_alarm		Temperature alarm.
110	temp1_crit		Critical chip temperature.
111	temp1_crit_alarm	Critical temperature high alarm.
112	temp1_highest		Highest observed temperature.
113	temp1_reset_history	Write any value to reset history.
114	
115				Temperature attributes are supported on ADM1278.
