Prefix: 'sch5627'
Addresses scanned: none, address read from Super I/O config space
Datasheet: Application Note available upon request

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.
