      coresight: replicator: retrieve and handle atclk · 9875cd9c
      Linus Walleij authored
      As can be seen from the datasheet of the CoreSight
      Components, DDI0314 table A-4 the funnel has a clock signal
      apart from the AHB interconnect ("amba_pclk", that we're
      already handling) called ATCLK, ARM Trace Clock, that SoC
      implementers may provide from an entirely different clock
      source. So to model this correctly create an optional
      path for handling ATCLK alongside the PCLK so we don't
      break old platforms that only define PCLK ("amba_pclk") but
      still makes it possible for SoCs that have both clock signals
      (such as the DB8500) to fetch and prepare/enable/disable/
      unprepare both clocks.
      
      The ATCLK is enabled and disabled using the runtime PM
      callbacks. As the replicator is a platform device, the
      code is a bit different from the other CoreSight components
      and the bus core does not activate runtime PM by default,
      so we need a few extra calls.
