    [ARM] Add clock API · 0471b5fb
    Russell King authored
    Since peripheral clocks are be derived in SoC or even platform
    specific ways, we need a way to keep this information out of the
    drivers.  AMBA Primecells are defined in terms of functional units
    where clocks are derived from external sources, and it is up to the
    SoC designer to determine where to derive those clocks from.
    
    Therefore, we provide a very basic API which allows platforms to
    provide this information in a generic manner to their peripherals.
    This framework also allows peripherals to shut down unused clock
    sources when they're not in use.
