QTI CPU isolation cooling devices.
|
||
|
|
|
||
|
|
The CPU isolation cooling device will be used for isolating a CPU on a thermal
|
||
|
|
condition. This cooling device driver can register one cooling device per CPU,
|
||
|
|
which can be used by thermal zone to mitigate.
|
||
|
|
|
||
|
|
Each child node will represent a cooling device and the child node should
|
||
|
|
point to the CPU, which will be mitigated by that cooling device instance.
