It consist of 3 values that are parsed: speedbin, psv and version. They are all appended to the opp-microvolt name and selected by the nvmem driver and loaded dynamically at runtime. Example: opp-microvolt-speed0-pvs0-v0 = <1050000 997500 1102500>; opp-microvolt-speed0-pvs1-v0 = <975000 926250 1023750>; opp-microvolt-speed0-pvs2-v0 = <925000 878750 971250>; opp-microvolt-speed0-pvs3-v0 = <850000 807500 892500>; Add support for this and reject these special binding if we don't have a nvmem-cell to read data from.
