Dear Mr./Ms.

I know i.mx6 has the thermal driver for preventing damage from over-heating of cpu.

In driver code, the alarm levels are 85 degree, 105 degre, It is only 2 step levels.


When the cpu temp. is reached to passive level (85), the cpu freq is set-up into the lowest freq. by the thermal driver right now.

There are four frequencies in the cpu freq table of i.mx6 1GHz version, so if the passive level is reached, it would be more efficient to adjust the cpu freq. step by step. Is there the method for a step-by-step adjustment?
