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