The tsens module enables reading of on chip sensors present in the Intel Bay series SoC. In the tsens module various junction temperature and SoC temperature are reported using thermal subsystem and i2c subsystem. Temperature data reported using thermal subsystem will be used for various cooling agents such as DVFS, fan control and shutdown the system in case of critical temperature. Temperature data reported using i2c subsytem will be used by platform manageability software running in remote host.
