    Subject[PATCH 2/3] dt-bindings: opp: opp-v2-kryo-cpu: add opp-microvolt nvmem based
    Date
    The operating-points-v2-kryo-cpu driver supports defining multiple
    opp-microvolt based on the blown efuses in the soc. 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.
