25	Description
26	-----------
27	
28	This driver supports hardware montoring for Analog Devices ADM1075, ADM1275,
29	ADM1276, ADM1293, and ADM1294 Hot-Swap Controller and Digital Power Monitors.
30	
31	ADM1075, ADM1275, ADM1276, ADM1293, and ADM1294 are hot-swap controllers that
32	allow a circuit board to be removed from or inserted into a live backplane.
33	They also feature current and voltage readback via an integrated 12
34	bit analog-to-digital converter (ADC), accessed using a PMBus interface.
35	
36	The driver is a client driver to the core PMBus driver. Please see
37	Documentation/hwmon/pmbus for details on PMBus client drivers.
38	
39	
40	Usage Notes
41	-----------
42	
43	This driver does not auto-detect devices. You will have to instantiate the
44	devices explicitly. Please see Documentation/i2c/instantiating-devices for
45	details.
46	
47	The ADM1075, unlike many other PMBus devices, does not support internal voltage
48	or current scaling. Reported voltages, currents, and power are raw measurements,
49	and will typically have to be scaled.
50	
51	
52	Platform data support
53	---------------------
54	
55	The driver supports standard PMBus driver platform data. Please see
56	Documentation/hwmon/pmbus for details.
57	
58	
59	Sysfs entries
60	-------------
61	
62	The following attributes are supported. Limits are read-write, history reset
63	attributes are write-only, all other attributes are read-only.
64	
65	inX_label		"vin1" or "vout1" depending on chip variant and
66				configuration. On ADM1075, ADM1293, and ADM1294,
67				vout1 reports the voltage on the VAUX pin.
68	inX_input		Measured voltage.
69	inX_min			Minimum Voltage.
70	inX_max			Maximum voltage.
71	inX_min_alarm		Voltage low alarm.
72	inX_max_alarm		Voltage high alarm.
73	inX_highest		Historical maximum voltage.
74	inX_reset_history	Write any value to reset history.
75	
76	curr1_label		"iout1"
77	curr1_input		Measured current.
78	curr1_max		Maximum current.
79	curr1_max_alarm		Current high alarm.
80	curr1_lcrit		Critical minimum current. Depending on the chip
81				configuration, either curr1_lcrit or curr1_crit is
82				supported, but not both.
83	curr1_lcrit_alarm	Critical current low alarm.
84	curr1_crit		Critical maximum current. Depending on the chip
85				configuration, either curr1_lcrit or curr1_crit is
86				supported, but not both.
87	curr1_crit_alarm	Critical current high alarm.
88	curr1_highest		Historical maximum current.
89	curr1_reset_history	Write any value to reset history.
90	
91	power1_label		"pin1"
92	power1_input		Input power.
93	power1_input_lowest	Lowest observed input power. ADM1293 and ADM1294 only.
94	power1_input_highest	Highest observed input power.
95	power1_reset_history	Write any value to reset history.
96	
97				Power attributes are supported on ADM1075, ADM1276,
98				ADM1293, and ADM1294.
