52	Description
53	-----------
54	
55	This driver supports hardware montoring for Intersil / Zilker Labs ZL6100 and
56	compatible digital DC-DC controllers.
57	
58	The driver is a client driver to the core PMBus driver. Please see
59	Documentation/hwmon/pmbus and Documentation.hwmon/pmbus-core for details
60	on PMBus client drivers.
61	
62	
63	Usage Notes
64	-----------
65	
66	This driver does not auto-detect devices. You will have to instantiate the
67	devices explicitly. Please see Documentation/i2c/instantiating-devices for
68	details.
69	
70	WARNING: Do not access chip registers using the i2cdump command, and do not use
71	any of the i2ctools commands on a command register used to save and restore
72	configuration data (0x11, 0x12, 0x15, 0x16, and 0xf4). The chips supported by
73	this driver interpret any access to those command registers (including read
74	commands) as request to execute the command in question. Unless write accesses
75	to those registers are protected, this may result in power loss, board resets,
76	and/or Flash corruption. Worst case, your board may turn into a brick.
77	
78	
79	Platform data support
80	---------------------
81	
82	The driver supports standard PMBus driver platform data.
83	
84	
85	Module parameters
86	-----------------
87	
88	delay
89	-----
90	
91	Intersil/Zilker Labs DC-DC controllers require a minimum interval between I2C
92	bus accesses. According to Intersil, the minimum interval is 2 ms, though 1 ms
93	appears to be sufficient and has not caused any problems in testing. The problem
94	is known to affect all currently supported chips. For manual override, the
95	driver provides a writeable module parameter, 'delay', which can be used to set
96	the interval to a value between 0 and 65,535 microseconds.
97

99	Sysfs entries
