+Registration of EM using DT
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The EM can also be registered using OPP framework and information in DT
+"operating-points-v2". Each OPP entry in DT can be extended with a property
+"opp-microwatt" containing micro-Watts power value. This OPP DT property
+allows a platform to register EM power values which are reflecting total power
+(static + dynamic). These power values might be coming directly from
+experiments and measurements.

Registration of 'simple' EM
~~~~~~~~~~~~~~~~~~~~~~~~~~~
The new registration method allows to get power values from the DT OPP definition. The new OPP entry property "opp-microwatt" contains total power expressed in micro-Watts. Align the EM documentation with this new possible registration method of EM.
