+title: Generic OPP (Operating Performance Points) v1 Bindings

+
+description: |+
+  Devices work at voltage-current-frequency combinations and some implementations
+  have the liberty of choosing these. These combinations are called Operating
+  Performance Points aka OPPs. This document defines bindings for these OPPs
+  applicable across wide range of devices. For illustration purpose, this document
+  uses CPU as a device.
+
+  This binding only supports voltage-frequency pairs.
