14	Description
15	-----------
16	
17	The LTC4215 controller allows a board to be safely inserted and removed
18	from a live backplane.
19	
20	
21	Usage Notes
22	-----------
23	
24	This driver does not probe for LTC4215 devices, due to the fact that some
25	of the possible addresses are unfriendly to probing. You will have to
26	instantiate the devices explicitly.
27	
28	Example: the following will load the driver for an LTC4215 at address 0x44
29	on I2C bus #0:
30	$ modprobe ltc4215
31	$ echo ltc4215 0x44 > /sys/bus/i2c/devices/i2c-0/new_device
32	
33	
34	Sysfs entries
35	-------------
36	
37	The LTC4215 has built-in limits for overvoltage, undervoltage, and
38	undercurrent warnings. This makes it very likely that the reference
39	circuit will be used.

41	in1_input		input voltage
42	in2_input		output voltage
43	
44	in1_min_alarm		input undervoltage alarm

46	
47	curr1_input		current
48	curr1_max_alarm		overcurrent alarm
49	
50	power1_input		power usage
