From d0351cc3b0f57214d157e4d589564730af2aedae Mon Sep 17 00:00:00 2001 From: Lukasz Luba Date: Wed, 27 May 2020 10:58:49 +0100 Subject: PM / EM: update callback structure and add device pointer The Energy Model framework is going to support devices other that CPUs. In order to make this happen change the callback function and add pointer to a device as an argument. Update the related users to use new function and new callback from the Energy Model.
