These are normally wired up through PDC so that the system can shut down
even if CPUSS is off

Here you have passive trip points with no passive polling, this will
only report threshold crossing events (so e.g. cpufreq throttling will
be broken)

+			trips {
+				trip-point0 {
+					temperature = <90000>;
+					hysteresis = <2000>;
+					type = "passive";
+				};
+
+				trip-point1 {
+					temperature = <95000>;
+					hysteresis = <2000>;
+					type = "passive";
+				};
+
+				cpu-critical {
+					temperature = <110000>;
+					hysteresis = <1000>;
+					type = "critical";
+				};
+			};
+		};

Here you have passive polling, but no passive trip point

+
+			thermal-sensors = <&tsens3 2>;
+
+			trips {
+				trip-point0 {
+					temperature = <90000>;
+					hysteresis = <2000>;
+					type = "hot";
+				};
+
+				nsp1-critical {
+					temperature = <125000>;
+					hysteresis = <0>;
+					type = "critical";
+				};
+			};
+		};


The rest looks okayish
