May we have more detail actions (ex: lower frequency) if reach alert and critical temperature point?
thermal-zones {
/* cpu thermal */
cpu-thermal {
polling-delay-passive = <250>;
polling-delay = <2000>;
thermal-sensors = <&tmu>;
trips {
cpu_alert0: trip0 {
temperature = <85000>;
hysteresis = <2000>;
type = "passive";
};
cpu_crit0: trip1 {
temperature = <95000>;
hysteresis = <2000>;
type = "critical";
};
};
cooling-maps {
map0 {
trip = <&cpu_alert0>;
cooling-device =
<&A53_0 THERMAL_NO_LIMIT THERMAL_NO_LIMIT>;
};
};
};
};
Solved! Go to Solution.
Hi m.c.
seems details can be found only in sources of thermal drivers described in
sect.2.9.3 Source Code Structure attached Linux Manual.

BTW: Looks like later NXP BSP releases now do have such settings available in the regular device tree:
