14	Description
15	-----------
16	
17	The LTC4151 is a High Voltage I2C Current and Voltage Monitor.
18	
19	
20	Usage Notes
21	-----------
22	
23	This driver does not probe for LTC4151 devices, since there is no register
24	which can be safely used to identify the chip. You will have to instantiate
25	the devices explicitly.
26	
27	Example: the following will load the driver for an LTC4151 at address 0x6f
28	on I2C bus #0:
29	# modprobe ltc4151
30	# echo ltc4151 0x6f > /sys/bus/i2c/devices/i2c-0/new_device

34	-------------
35	
36	Voltage readings provided by this driver are reported as obtained from the ADIN
37	and VIN registers.
38	
39	Current reading provided by this driver is reported as obtained from the Current
40	Sense register. The reported value assumes that a 1 mOhm sense resistor is
41	installed.
