From 4422d1322a8ed47bc9d743894ad47d82f33eba7c Mon Sep 17 00:00:00 2001 From: Stephan Diestelhorst Date: Mon, 16 Jun 2014 14:59:44 +0100 Subject: energy: Small extentions and fixes for DVFS handler These additions allow easier interoperability with and querying from an additional controller which will be in a separate patch. Also adding warnings for changing the enabled state of the handler across checkpoint / resume and deviating from the state in the configuration.
