14	Description
15	-----------
16	
17	This driver implements support for the Maxim MAX6639. This chip is a 2-channel
18	temperature monitor with dual PWM fan speed controller. It can monitor its own
19	temperature and one external diode-connected transistor or two external
20	diode-connected transistors.
21	
22	The following device attributes are implemented via sysfs:
