      ASoC: rt5631: Fix regcache sync errors on resume · c71f78a6
      Maxim Schwalm authored
      The ALC5631 does not like multi-write accesses, avoid them. This fixes:
      
      rt5631 4-001a: Unable to sync registers 0x3a-0x3c. -121
      
      errors on resume from suspend (and all registers after the registers in
      the error not being synced).
      
      Inspired by commit 2d30e949 ("ASoC: rt5651: Fix regcache sync errors
      on resume") from Hans de Geode, which fixed the same errors on ALC5651.

      This small series addresses a minor issue with how IOMMU support is
      wired up on various Tegra generations. Currently the virtual "card"
      device is used to allocate DMA memory for, but since that device does
      not actually exist, the path to memory cannot be correctly described.
      
      To address this, this series moves to using the ADMAIF as the DMA device
      for audio. This is a real device that can have a proper DMA mask set and
      with which a stream ID can be associated with in the SMMU. The memory
      accesses technically originate from the ADMA controller (that the ADMAIF
      uses), but DMA channel are dynamically allocated at runtime while DMA
      memory is allocated at driver load time, drivers won't have access to
      the ADMA device yet.
      
      Further patches will be required to correct this issue on Tegra186 and
      Tegra210, but I wanted to get feedback on this approach first.
      
      Changes in v2:
      - add backwards-compatibility fallback
