      ASoC: arizona: Add support for SNDRV_PCM_RATE_KNOT · d81221ff
      Charles Keepax 提交于
      The Arizona CODECs support several rates that do not have simple defines
      in ALSA. This patch adds support for SNDRV_PCM_RATE_KNOT so that users
      can open stream at these rates. As part of this we should always set
      constraints in arizona_startup, currently we only set the constraints if
      we already have a clock to limit rates to that family of sample rates.
      This patch updates this to set a constraint of all rates supported by
      the chip if we do not already know which family of rates to limit to.
      Finally we also reduce the list of rates supported in the constraints to
      only include those that are supported on current parts.

      ASoC: arizona: Export functions to control subsystem DVFS · 346d9683
      Richard Fitzgerald 提交于
      The WM5102 and WM8997 codecs have an internal dynamic clock booster.
      When this booster is active, the DCVDD voltage must be increased.
      If all the currently active audio paths can run with the root SYSCLK
      we can disable the booster, allowing us to turn down DCVDD voltage
      to save power.
      
      Previously this was being done by having the booster enable bit set
      as a side-effect of the LDO1 regulator driver, which is unexpected
      behaviour of a regulator and not compatible with using an external
      regulator.  [Originally this was documented as a feature of the internal
      LDO -- broonie]
      
      This patch exports functions to handle the booster enable and
      DCVDD voltage, with each relevant subsystem flagging whether it can
      currently run without the booster. Note that these subsystems are
      stateless and none of them are nestable, so there's no need for
      reference counting, we only need a simple boolean for each subsystem
      of whether their current condition could require the booster or will
      allow us to turn the codec down to lower operating power.
