[PATCH V2] thermal/drivers/step_wise: Fix temperature regulation misbehavior

2017-09-08 Thread Daniel Lezcano
There is a particular situation when the cooling device is cpufreq and the heat dissipation is not efficient enough where the temperature increases little by little until reaching the critical threshold and leading to a SoC reset. The behavior is reproducible on a hikey6220 with bad heat
