13	Description
14	-----------
16	LTC2990 is a Quad I2C Voltage, Current and Temperature Monitor.
17	The chip's inputs can measure 4 voltages, or two inputs together (1+2 and 3+4)
18	can be combined to measure a differential voltage, which is typically used to
19	measure current through a series resistor, or a temperature.
21	This driver currently uses the 2x differential mode only. In order to support
22	other modes, the driver will need to be expanded.
25	Usage Notes
26	-----------
28	This driver does not probe for PMBus devices. You will have to instantiate
29	devices explicitly.
32	Sysfs attributes
33	----------------
35	The "curr*_input" measurements actually report the voltage drop across the
36	input pins in microvolts. This is equivalent to the current through a 1mOhm
37	sense resistor. Divide the reported value by the actual sense resistor value
38	in mOhm to get the actual value.
40	in0_input     Voltage at Vcc pin in millivolt (range 2.5V to 5V)
41	temp1_input   Internal chip temperature in millidegrees Celcius
42	curr1_input   Current in mA across v1-v2 assuming a 1mOhm sense resistor.
43	curr2_input   Current in mA across v3-v4 assuming a 1mOhm sense resistor.
