14	Description
15	-----------
16	
17	The LTC4260 Hot Swap controller allows a board to be safely inserted
18	and removed from a live backplane.
19	
20	
21	Usage Notes
22	-----------
23	
24	This driver does not probe for LTC4260 devices, since there is no register
25	which can be safely used to identify the chip. You will have to instantiate
26	the devices explicitly.
27	
28	Example: the following will load the driver for an LTC4260 at address 0x10
29	on I2C bus #1:
30	$ modprobe ltc4260
31	$ echo ltc4260 0x10 > /sys/bus/i2c/devices/i2c-1/new_device

35	-------------

37	Voltage readings provided by this driver are reported as obtained from the ADC
38	registers. If a set of voltage divider resistors is installed, calculate the
39	real voltage by multiplying the reported value with (R1+R2)/R2, where R1 is the
40	value of the divider resistor against the measured voltage and R2 is the value
41	of the divider resistor against Ground.
42	
43	Current reading provided by this driver is reported as obtained from the ADC
44	Current Sense register. The reported value assumes that a 1 mOhm sense resistor
45	is installed. If a different sense resistor is installed, calculate the real
46	current by dividing the reported value by the sense resistor value in mOhm.
47	
48	in1_input		SOURCE voltage (mV)
49	in1_min_alarm		Undervoltage alarm
50	in1_max_alarm		Overvoltage alarm
51	
52	in2_input		ADIN voltage (mV)
53	in2_alarm		Power bad alarm
54	
55	curr1_input		SENSE current (mA)
56	curr1_alarm		SENSE overcurrent alarm
