Hi, The series adds support for thermal management on ARM Juno development platform. As part of this development, common infrastructure is added to support registering cpu cooling devices that work with the power allocator thermal governor. Patch 1 extends the CPU nodes binding to provide an optional dynamic power coefficient which can be used to create a dynamic power model for the CPUs. This model is used to constrain device power consumption (using power_allocator governor) when the system is thermally constrained. Patches 2-3 extends the cpufreq-dt and arm_big_little driver to register cpu cooling devices with the dynamic coefficient when provided. Patches 4-7 create a hwmon sensor driver for sensors provided by SCPI firmware. Patch 7 adds support for the temperature sensors to register with the thermal framework. This allows setting up platform thermals using OF thermal bindings. The last two patches add support for the sensors and the thermal zones in the Juno device tree. The Juno specific patches depend on SCPI and cpufreq patches[0] from Sudeep.
