| |
The thermal cooling device specified in DT might be instantiated for a thermal zone trip point with a limited set of OPPs to operate on. This configuration should be supported by Intelligent Power Allocation (IPA), since it is a standard for other governors. Change the code and allow IPA to get power value of lower and upper bound set for a given cooling device.
