Dmitry Osipenko 16e8b2a7cb PM / devfreq: tegra30: Support interconnect and OPPs from device-tree
This patch moves ACTMON driver away from generating OPP table by itself,
transitioning it to use the table which comes from device-tree. This
change breaks compatibility with older device-trees and brings support
for the interconnect framework to the driver. This is a mandatory change
which needs to be done in order to implement interconnect-based memory
DVFS, i.e. device-trees need to be updated. Now ACTMON issues a memory
bandwidth requests using dev_pm_opp_set_bw() instead of driving EMC clock
rate directly.
