|
Certain Cooling devices reside in userspace and they also needs to be
|
|
mitigated for thermal conditions. Thermal framework will send netlink message
|
|
to userspace, when a cooling device level changes for any cooling device.
|
|
This cooling device expects the userspace cooling device to listen to the
|
|
netlink message and take necessary action.
|
|
|
|
Devicetree will define the name of the cooling device and the max mitigation
|
|
level a cooling device can support. Each child node will be an individual
|
|
cooling device.

This child node describes the maximum level supported.

Minimum one child node is required. Child node name is used as

cooling device name and phandle for that cooling device.
