From: Mathieu Poirier <[email protected]> This patchset is using the runtime PM API and the generic power domain sub-system to prevent coresight power domains from being switched off while trace scenarios are still being executed.
This is supplemented with the creation of two new generic power domains for the big and LITTLE clusters on the vexpress-tc2 platform. By adding coresigth tracers to the power domain they belong to and using the new generic power domain logic in the spc driver, clusters are kept powered for as long as coresight operations are ongoing.
