Description
-----------
This driver implements support for the hardware sensor capabilities
-of the SMSC LPC47M192 and LPC47M997 Super-I/O chips.
+of the SMSC LPC47M192 and compatible Super-I/O chips.
These chips support 3 temperature channels and 8 voltage inputs
as well as CPU voltage VID input.
sysfs interface

-in0_input - +2.5V voltage input
-in1_input - CPU voltage input (nominal 2.25V)
-in2_input - +3.3V voltage input
-in3_input - +5V voltage input
-in4_input - +12V voltage input (may be missing if used as VID4)
-in5_input - Vcc voltage input (nominal 3.3V)
- This is the supply voltage of the sensor chip itself.
-in6_input - +1.5V voltage input
-in7_input - +1.8V voltage input

- Note that temp1 and temp2 offsets share the same register,
- they cannot both be different from zero at the same time.
- Writing a non-zero number to one of them will reset the other
- offset to zero.
