7 title: Generic OPP (Operating Performance Points) v1
10 - Viresh Kumar <viresh.kumar@linaro.org>
13 Devices work at voltage-current-frequency combinations and some implementations
14 have the liberty of choosing these. These combinations are called Operating
15 Performance Points aka OPPs. This document defines bindings for these OPPs
16 applicable across wide range of devices. For illustration purpose, this document
19 This binding only supports voltage-frequency pairs.
