    Subject[PATCH v11 1/9] dt-bindings: opp: Introduce opp-level bindings
    Date
    Add opp-level as an additional property in the OPP node to describe
    the performance level of the device.

    On some SoCs (especially from Qualcomm and MediaTek) this value
    is communicated to a remote microprocessor by the CPU, which
    then takes some actions (like adjusting voltage values across various
    rails) based on the value passed.
