[PATCH v2 1/4] OMAP OPP: Add accessor function for getting OPP ID.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add new function opp_get_opp_id() for finding the OPP ID of a given
OPP.  This allows us to further hide OPP layer details.

NOTE: OPP IDs are deprecated, and this function will eventually
      be removed after all users of OPP IDs are removed.
