18	Description
19	-----------
20	
21	This driver supports hardware montoring for Maxim MAX34440 PMBus 6-Channel
22	Power-Supply Manager and MAX34441 PMBus 5-Channel Power-Supply Manager
23	and Intelligent Fan Controller.
24	
25	The driver is a client driver to the core PMBus driver. Please see
26	Documentation/hwmon/pmbus for details on PMBus client drivers.
27	
28	
29	Usage Notes
30	-----------
31	
32	This driver does not auto-detect devices. You will have to instantiate the
33	devices explicitly. Please see Documentation/i2c/instantiating-devices for
34	details.

37	Platform data support
38	---------------------
39	
40	The driver supports standard PMBus driver platform data.
41	
42	
43	Sysfs entries
44	-------------
45	
46	The following attributes are supported. Limits are read-write; all other
47	attributes are read-only.
48	
49	in[1-6]_label		"vout[1-6]".
50	in[1-6]_input		Measured voltage. From READ_VOUT register.
51	in[1-6]_min		Minumum Voltage. From VOUT_UV_WARN_LIMIT register.
52	in[1-6]_max		Maximum voltage. From VOUT_OV_WARN_LIMIT register.
53	in[1-6]_lcrit		Critical minumum Voltage. VOUT_UV_FAULT_LIMIT register.
54	in[1-6]_crit		Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register.
55	in[1-6]_min_alarm	Voltage low alarm. From VOLTAGE_UV_WARNING status.
56	in[1-6]_max_alarm	Voltage high alarm. From VOLTAGE_OV_WARNING status.
57	in[1-6]_lcrit_alarm	Voltage critical low alarm. From VOLTAGE_UV_FAULT status.
58	in[1-6]_crit_alarm	Voltage critical high alarm. From VOLTAGE_OV_FAULT status.
59	in[1-6]_highest		Historical maximum voltage.
60	in[1-6]_reset_history	Write any value to reset history.
61	
62	curr[1-6]_label		"iout[1-6]".
63	curr[1-6]_input		Measured current. From READ_IOUT register.
64	curr[1-6]_max		Maximum current. From IOUT_OC_WARN_LIMIT register.
65	curr[1-6]_crit		Critical maximum current. From IOUT_OC_FAULT_LIMIT register.
66	curr[1-6]_max_alarm	Current high alarm. From IOUT_OC_WARNING status.
67	curr[1-6]_crit_alarm	Current critical high alarm. From IOUT_OC_FAULT status.
68	curr[1-6]_highest	Historical maximum current.
69	curr[1-6]_reset_history	Write any value to reset history.
70	
71				in6 and curr6 attributes only exist for MAX34440.
72	
73	temp[1-8]_input		Measured temperatures. From READ_TEMPERATURE_1 register.
74				temp1 is the chip's internal temperature. temp2..temp5
75				are remote I2C temperature sensors. For MAX34441, temp6
76				is a remote thermal-diode sensor. For MAX34440, temp6..8
77				are remote I2C temperature sensors.
78	temp[1-8]_max		Maximum temperature. From OT_WARN_LIMIT register.
79	temp[1-8]_crit		Critical high temperature. From OT_FAULT_LIMIT register.
80	temp[1-8]_max_alarm	Temperature high alarm.
81	temp[1-8]_crit_alarm	Temperature critical high alarm.
82	temp[1-8]_highest	Historical maximum temperature.
83	temp[1-8]_reset_history	Write any value to reset history.
84	
85				temp7 and temp8 attributes only exist for MAX34440.
