0001 * ST-Ericsson DB8500 Thermal
0002
0003 ** Thermal node properties:
0004
0005 - compatible : "stericsson,db8500-thermal";
0006 - reg : address range of the thermal sensor registers;
0007 - interrupts : interrupts generated from PRCMU;
0008 - interrupt-names : "IRQ_HOTMON_LOW" and "IRQ_HOTMON_HIGH";
0009 - num-trips : number of total trip points, this is required, set it 0 if none,
0010 if greater than 0, the following properties must be defined;
0011 - tripN-temp : temperature of trip point N, should be in ascending order;
0012 - tripN-type : type of trip point N, should be one of "active" "passive" "hot"
0013 "critical";
0014 - tripN-cdev-num : number of the cooling devices which can be bound to trip
0015 point N, this is required if trip point N is defined, set it 0 if none,
0016 otherwise the following cooling device names must be defined;
0017 - tripN-cdev-nameM : name of the No. M cooling device of trip point N;
0018
0019 Usually the num-trips and tripN-*** are separated in board related dts files.
