60	Description
61	-----------
62	
63	This driver supports hardware montoring for Intersil / Zilker Labs ZL6100 and
64	compatible digital DC-DC controllers.
65	
66	The driver is a client driver to the core PMBus driver. Please see
67	Documentation/hwmon/pmbus and Documentation.hwmon/pmbus-core for details
68	on PMBus client drivers.
69	
70	
71	Usage Notes
72	-----------
73	
74	This driver does not auto-detect devices. You will have to instantiate the
75	devices explicitly. Please see Documentation/i2c/instantiating-devices for
76	details.
77	
78	WARNING: Do not access chip registers using the i2cdump command, and do not use
79	any of the i2ctools commands on a command register used to save and restore
80	configuration data (0x11, 0x12, 0x15, 0x16, and 0xf4). The chips supported by
81	this driver interpret any access to those command registers (including read
82	commands) as request to execute the command in question. Unless write accesses
83	to those registers are protected, this may result in power loss, board resets,
84	and/or Flash corruption. Worst case, your board may turn into a brick.
85	
86	
87	Platform data support
88	---------------------
89	
90	The driver supports standard PMBus driver platform data.
91	
92	
93	Module parameters
94	-----------------
95	
96	delay
97	-----
98	
99	Intersil/Zilker Labs DC-DC controllers require a minimum interval between I2C
100	bus accesses. According to Intersil, the minimum interval is 2 ms, though 1 ms
101	appears to be sufficient and has not caused any problems in testing. The problem
102	is known to affect all currently supported chips. For manual override, the
103	driver provides a writeable module parameter, 'delay', which can be used to set
104	the interval to a value between 0 and 65,535 microseconds.
105	
106	
107	Sysfs entries
108	-------------
109	
110	The following attributes are supported. Limits are read-write; all other
111	attributes are read-only.
112	
113	in1_label		"vin"
114	in1_input		Measured input voltage.
115	in1_min			Minimum input voltage.
116	in1_max			Maximum input voltage.
117	in1_lcrit		Critical minimum input voltage.
118	in1_crit		Critical maximum input voltage.
119	in1_min_alarm		Input voltage low alarm.
120	in1_max_alarm		Input voltage high alarm.
121	in1_lcrit_alarm		Input voltage critical low alarm.
122	in1_crit_alarm		Input voltage critical high alarm.
123	
124	in2_label		"vmon"
125	in2_input		Measured voltage on VMON (ZL2004) or VDRV (ZL9101M,
126				ZL9117M) pin. Reported voltage is 16x the voltage on the
127				pin (adjusted internally by the chip).
128	in2_lcrit		Critical minimum VMON/VDRV Voltage.
129	in2_crit		Critical maximum VMON/VDRV voltage.
130	in2_lcrit_alarm		VMON/VDRV voltage critical low alarm.
131	in2_crit_alarm		VMON/VDRV voltage critical high alarm.
132	
133				vmon attributes are supported on ZL2004, ZL9101M,
134				and ZL9117M only.
135	
136	inX_label		"vout1"
137	inX_input		Measured output voltage.
138	inX_lcrit		Critical minimum output Voltage.
139	inX_crit		Critical maximum output voltage.
140	inX_lcrit_alarm		Critical output voltage critical low alarm.
141	inX_crit_alarm		Critical output voltage critical high alarm.
142	
143				X is 3 for ZL2004, ZL9101M, and ZL9117M, 2 otherwise.
144	
145	curr1_label		"iout1"
146	curr1_input		Measured output current.
147	curr1_lcrit		Critical minimum output current.
148	curr1_crit		Critical maximum output current.
149	curr1_lcrit_alarm	Output current critical low alarm.
150	curr1_crit_alarm	Output current critical high alarm.
151	
152	temp[12]_input		Measured temperature.
153	temp[12]_min		Minimum temperature.
154	temp[12]_max		Maximum temperature.
155	temp[12]_lcrit		Critical low temperature.
156	temp[12]_crit		Critical high temperature.
157	temp[12]_min_alarm	Chip temperature low alarm.
158	temp[12]_max_alarm	Chip temperature high alarm.
159	temp[12]_lcrit_alarm	Chip temperature critical low alarm.
160	temp[12]_crit_alarm	Chip temperature critical high alarm.
