13	Description
14	-----------
15	
16	This driver supports hardware montoring for Maxim MAX8688 Digital Power-Supply
17	Controller/Monitor with PMBus Interface.
18	
19	The driver is a client driver to the core PMBus driver. Please see
20	Documentation/hwmon/pmbus for details on PMBus client drivers.
21	
22	
23	Usage Notes
24	-----------
25	
26	This driver does not auto-detect devices. You will have to instantiate the
27	devices explicitly. Please see Documentation/i2c/instantiating-devices for
28	details.

31	Platform data support
32	---------------------
33	
34	The driver supports standard PMBus driver platform data.
35	
36	
37	Sysfs entries
38	-------------
39	
40	The following attributes are supported. Limits are read-write; all other
41	attributes are read-only.
42	
43	in1_label		"vout1"
44	in1_input		Measured voltage. From READ_VOUT register.
45	in1_min			Minimum Voltage. From VOUT_UV_WARN_LIMIT register.
46	in1_max			Maximum voltage. From VOUT_OV_WARN_LIMIT register.
47	in1_lcrit		Critical minimum Voltage. VOUT_UV_FAULT_LIMIT register.
48	in1_crit		Critical maximum voltage. From VOUT_OV_FAULT_LIMIT register.
49	in1_min_alarm		Voltage low alarm. From VOLTAGE_UV_WARNING status.
50	in1_max_alarm		Voltage high alarm. From VOLTAGE_OV_WARNING status.
51	in1_lcrit_alarm		Voltage critical low alarm. From VOLTAGE_UV_FAULT status.
52	in1_crit_alarm		Voltage critical high alarm. From VOLTAGE_OV_FAULT status.
53	in1_highest		Historical maximum voltage.
54	in1_reset_history	Write any value to reset history.
55	
56	curr1_label		"iout1"
57	curr1_input		Measured current. From READ_IOUT register.
58	curr1_max		Maximum current. From IOUT_OC_WARN_LIMIT register.
59	curr1_crit		Critical maximum current. From IOUT_OC_FAULT_LIMIT register.
60	curr1_max_alarm		Current high alarm. From IOUT_OC_WARN_LIMIT register.
61	curr1_crit_alarm	Current critical high alarm. From IOUT_OC_FAULT status.
62	curr1_highest		Historical maximum current.
63	curr1_reset_history	Write any value to reset history.
64	
65	temp1_input		Measured temperature. From READ_TEMPERATURE_1 register.
66	temp1_max		Maximum temperature. From OT_WARN_LIMIT register.
67	temp1_crit		Critical high temperature. From OT_FAULT_LIMIT register.
68	temp1_max_alarm		Chip temperature high alarm. Set by comparing
69				READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING
70				status is set.
71	temp1_crit_alarm	Chip temperature critical high alarm. Set by comparing
72				READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT
73				status is set.
74	temp1_highest		Historical maximum temperature.
75	temp1_reset_history	Write any value to reset history.
