+* ST-Ericsson DB8500 Thermal
+
+** Thermal node properties:
+
+- compatible : "stericsson,db8500-thermal";
+- reg : address range of the thermal sensor registers;
+- interrupts : interrupts generated form PRCMU;
+- interrupt-names : "IRQ_HOTMON_LOW" and "IRQ_HOTMON_HIGH";
+- num-trips : number of total trip points;
+- tripN-temp : temperature of trip point N;
+- tripN-type : type of trip point N, should be one of "active" "passive" "hot" "critical";
+- tripN-cdev-num : number of the cooling devices which can be bound to trip point N;
+- tripN-cdev-nameM : name of the No. M cooling device of trip point N;
+
+Usually the num-trips and tripN-*** are seperated in board related dts files.
+
