description: |
|
|
The CPU pause cooling device will be used for isolating a CPU on a thermal
|
|
condition. This cooling device driver can register one cooling device per
|
|
single or multiple CPUs, 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 mask, which will be mitigated by that cooling device instance.
