Add support for the watchdog integrated into the SMSC SCH5627 and SCH5636 superio-s. Since the watchdog is part of the hwmon logical device and thus shares ioports with it, the watchdog driver is integrated into the existing hwmon drivers for these. Note that this version of the watchdog support for sch56xx superio-s implements the watchdog chardev interface itself, rather then relying on the recently added watchdog core / watchdog_dev. This is done because currently some needed functionality is missing from watchdog_dev, as soon as this functionality is added (which is being discussed on the linux-watchdog mailinglist), I'll convert this driver over to using watchdog_dev.

Description
|
|
-----------
|
|
|
|
SMSC SCH5636 Super I/O chips include an embedded microcontroller for
|
|
hardware monitoring solutions, allowing motherboard manufacturers to create
|
|
their own custom hwmon solution based upon the SCH5636.
|
|
|
|
Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636 based
|
|
hwmon solution. The sch5636 driver runs a sanity check on loading to ensure
|
|
it is dealing with a Fujitsu Theseus and not with another custom SCH5636 based
|
|
hwmon solution.
|
|
|
|
The Fujitsu Theseus can monitor up to 5 voltages, 8 fans and 16
|
|
temperatures. Note that the driver detects how many fan headers /
|
|
temperature sensors are actually implemented on the motherboard, so you will
|
|
likely see fewer temperature and fan inputs.
|
|
|
|
The Fujitsu Theseus hwmon solution also contains an integrated watchdog.
|
|
This watchdog is fully supported by the sch5636 driver.

An application note describing the Theseus' registers, as well as an
|
|
application note describing the protocol for communicating with the
|
|
microcontroller is available upon request. Please mail me if you want a copy.
