   2
   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
  19 Usually the num-trips and tripN-*** are separated in board related dts files.
