   3** Thermal node properties:
   4
   5- compatible : "stericsson,db8500-thermal";
   6- reg : address range of the thermal sensor registers;
   7- interrupts : interrupts generated from PRCMU;
   8- interrupt-names : "IRQ_HOTMON_LOW" and "IRQ_HOTMON_HIGH";
   9- num-trips : number of total trip points, this is required, set it 0 if none,
  10  if greater than 0, the following properties must be defined;
  11- tripN-temp : temperature of trip point N, should be in ascending order;
  12- tripN-type : type of trip point N, should be one of "active" "passive" "hot"
  13  "critical";
  14- tripN-cdev-num : number of the cooling devices which can be bound to trip
  15  point N, this is required if trip point N is defined, set it 0 if none,
  16  otherwise the following cooling device names must be defined;
  17- tripN-cdev-nameM : name of the No. M cooling device of trip point N;
  18
  19Usually the num-trips and tripN-*** are separated in board related dts files.
