If you say yes here you get support for the following Fujitsu
Siemens Computers (FSC) sensor chips: Poseidon, Scylla, Hermes,
Heimdall, Heracles and Syleus including support for the integrated
watchdog.
Heimdall, Heracles, Hades and Syleus including support for the
integrated watchdog.

This is a merged driver for FSC sensor chips replacing the fscpos,
fscscy and fscher drivers and adding support for several other FSC
