| 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>; |
| 44 | } |
