 Description
 -----------
 
 This driver implements support for the hardware monitoring capabilities of the
-SMSC DME1737 and Asus A8000 (which are the same) and SMSC SCH311x Super-I/O
-chips. These chips feature monitoring of 3 temp sensors temp[1-3] (2 remote
-diodes and 1 internal), 7 voltages in[0-6] (6 external and 1 internal) and up
-to 6 fan speeds fan[1-6]. Additionally, the chips implement up to 5 PWM
-outputs pwm[1-3,5-6] for controlling fan speeds both manually and
