Description
-----------
This driver implements support for the Fujitsu Siemens Poseidon chip.
It is descibed in the 'Register Set Specification BMC Poseidon based
Systemboard' from Fujitsu Siemens.
The poseidon chip implements a hardware based system management,
e.g. for controlling fan speed and core voltage.
There is also a watchdog counter on the chip which can trigger
an alarm and even shutdown the system.
The chip provides three temperature values (cpu, motherboard and auxiliary),
three current values (12 volt, 5 volt and battery) and
three fans (power supply, cpu and auxiliary).
Temperatures are measured in degrees Celcius. The resolution is 1 degree.
FAN rotation speeds are reported in RPM (rotations per minute).
The value can be divided by a programmable divider (1, 2, 4 or 8) which
is stored on the chip.
Voltage sensors (also known as IN sensors) report their values in volts.
All values are reported as final values from the driver.
There is no need for further calculations.
