Detailed Description

Thermo-control driver.

The Thermo controll can works both with kernel or without it. In the case we use kernel, the thermo controll is done by one process that poll every CONFIG_THERMO_INTERVAL_MS the temperature sensor and make all operation to follow the target temperature. While we not use the kernel the module works with one timer interrupt in the same way of the kenel case.
