Subject[RFC PATCH 2/4] dt-bindings: ufs: common: allow OPP table
Date
Except scaling UFS and bus clocks, it's necessary to scale also the
voltages of regulators or power domain performance state levels. Adding
Operating Performance Points table allows to adjust power domain
performance state, depending on the UFS clock speed.
