-Kernel driver sch5627
-=====================
-
-Supported chips:
- * SMSC SCH5627
- Prefix: 'sch5627'
- Addresses scanned: none, address read from Super I/O config space
- Datasheet: Application Note available upon request
-
-Author: Hans de Goede <hdegoede@redhat.com>
-
-
-Description
------------
-
-SMSC SCH5627 Super I/O chips include complete hardware monitoring
-capabilities. They can monitor up to 5 voltages, 4 fans and 8 temperatures.
-
-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.
