description: |
|
|
The QMI TMD cooling device, will be used for various mitigations for remote
|
|
subsystem including remote processor mitigation, rail voltage restriction etc.
|
|
This cooling device uses kernel qti QMI interface to send the message to
|
|
remote subsystem.
|
|
|
|
Each child node of the QMI TMD devicetree node represents each remote
|
|
subsystem and each child of this subsystem represents separate cooling
|
|
devices. It requires minimum one remote subsystem node and each subsystem
|
|
node requires minimum one cooling device node.
