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. |
