1	* ST-Ericsson DB8500 Thermal
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.

21	Example:
22	thermal@801573c0 {
23		compatible = "stericsson,db8500-thermal";
24		reg = <0x801573c0 0x40>;
25		interrupts = <21 0x4>, <22 0x4>;
26		interrupt-names = "IRQ_HOTMON_LOW", "IRQ_HOTMON_HIGH";
27	
28		num-trips = <3>;
29	
30		trip0-temp = <75000>;
31		trip0-type = "active";
32		trip0-cdev-num = <1>;
33		trip0-cdev-name0 = "thermal-cpufreq-0";
34	
35		trip1-temp = <80000>;
36		trip1-type = "active";
37		trip1-cdev-num = <2>;
38		trip1-cdev-name0 = "thermal-cpufreq-0";
39		trip1-cdev-name1 = "thermal-fan";
40	
41		trip2-temp = <85000>;
42		trip2-type = "critical";
43		trip2-cdev-num = <0>;
