Description
-----------
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
-controlling fan speeds both manually and automatically.
+SMSC DME1737 and Asus A8000 (which are the same), SMSC SCH5027, 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, A8000 and SCH5027, 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.
-Fan[3-6] and pwm[3,5-6] are optional features and their availability is
-dependent on the configuration of the chip. The driver will detect which
-features are present during initialization and create the sysfs attributes
-accordingly.
+The hardware monitoring features of the DME1737, A8000, and SCH5027 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, A8000, or SCH5027 and as a platform driver if it detects a SCH311x
+chip.
