Ok, so apparently there are multiple alarms level in the driver for the hikey960 [1]. So I prefer to drop this patch for now and take the hikey960 thermal support first and we can sort out the issue later. For my information, can you show me the DT snippet you have for the thermal zones?
Sure thing:
thermal-zones {
cls0: cls0 {
polling-delay = <1000>;
polling-delay-passive = <100>;
sustainable-power = <4500>;
/* sensor ID */
thermal-sensors = <&tsensor 1>;
trips {
threshold: trip-point@0 {
temperature = <65000>;
hysteresis = <1000>;
type = "passive";
};
target: trip-point@1 {
temperature = <75000>;
hysteresis = <1000>;
type = "passive";
};
};
cooling-maps {
map0 {
trip = <&target>;
contribution = <1024>;
cooling-device = <&cpu0 THERMAL_NO_LIMIT
THERMAL_NO_LIMIT>;
};
map1 {
trip = <&target>;
contribution = <512>;
cooling-device = <&cpu4 THERMAL_NO_LIMIT
THERMAL_NO_LIMIT>;
};
map2 {
trip = <&target>;
contribution = <1024>;
cooling-device = <&gpu THERMAL_NO_LIMIT
THERMAL_NO_LIMIT>;
};
};
};
};
It's exactly what is on the Android 4.9 kernel
(https://android.googlesource.com/kernel/hikey-linaro/+/android-hikey-linaro-4.9/arch/arm64/boot/dts/hisilicon/hi3660.dtsi#1272),
with the tsensor index changed from 4 to 1 to work with Kevin's patches.
