But as QCS9075 is non-safe SoC it requires conventional thermal mitigation to control thermal for different subsystems. The cpu frequency throttling for different cpu tsens is enabled in hardware as first defense for cpu thermal control. But QCS9075 SoC has higher ambient specification. During high ambient condition, even lowest frequency with multi cores can slowly build heat over the time and it can lead to thermal run-away situations. This patch restrict cpu cores during this scenario helps further thermal control and avoids thermal critical violation. Add cpu idle injection cooling bindings for cpu tsens thermal zones as a mitigation for cpu subsystem prior to thermal shutdown. Add cpu frequency cooling devices that will be used by userspace thermal governor to mitigate skin thermal management.
