+Description
+-----------
+
+SMSC SCH5627 Super I/O chips include complete hardware monitoring
+capabilities. They can monitor up to 5 voltages, 4 fans and 8 temperatures.
+
+In addition, the SCH5627 exports data describing which temperature sensors
+affect the speed of each fan. Setting pwmX_auto_channels_temp to 0 forces
+the corresponding fan to full speed until another value is written.
+
+The SMSC SCH5627 hardware monitoring part also contains an integrated
+watchdog. In order for this watchdog to function some motherboard specific
+initialization most be done by the BIOS, so if the watchdog is not enabled
+by the BIOS the sch5627 driver will not register a watchdog device.
+
+The hardware monitoring part of the SMSC SCH5627 is accessed by talking
+through an embedded microcontroller. An application note describing the
+protocol for communicating with the microcontroller is available upon
+request. Please mail me if you want a copy.
