 This driver implements support for the hardware monitoring capabilities of the
-SMSC DME1737 and Asus A8000 (which are the same) Super-I/O chips. This chip
-features 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 6 fan speeds
-fan[1-6]. Additionally, the chip implements 5 PWM outputs pwm[1-3,5-6] for

+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
+automatically.
+
+For the DME1737 and A8000, fan[1-2] and pwm[1-2] are always present. Fan[3-6]
+and pwm[3,5-6] are optional features and their availability depends on the
+configuration of the chip. The driver will detect which features are present
+during initialization and create the sysfs attributes accordingly.
+
+For the SCH311x, fan[1-3] and pwm[1-3] are always present and fan[4-6] and
+pwm[5-6] don't exist.
+
+The hardware monitoring features of the DME1737 and A8000 are only accessible
+via SMBus, while the SCH311x only provides access via the ISA bus. The driver
+will therefore register itself as an I2C client driver if it detects a DME1737
+or A8000 and as a platform driver if it detects a SCH311x chip.
