Hi all, This patch set solves a few issues: 1. It allows to register EM from DT, when the voltage information is not available. (Some background of the issues present on Chromebook devices can be checked at [1].) 2. It allows to register 'advanced' EM from the DT, which is more accurate and reflects total power (dynamic + static). Implementation details: It adds a new callback in OPP framework to parse the "energy-model" DT entry. The propsed DT bindings heavily draw on "operating-points" (v1) schema. Comments, suggestions are very welcome.
