      ASoC: stm32: spdifrx: change trace level on iec control · 19e42536
      Olivier Moysan authored
      Change trace level to debug to avoid spurious messages.
      Return quietly when accessing iec958 control, while no
      S/PDIF signal is available.

      ASoC: stm32: spdifrx: update pcm hardware constraints · 863137f0
      Olivier Moysan authored
      - Set period minimum size. Ensure at least 5ms period
      up to 48kHz/16 bits to prevent underrun/overrun.
      - Remove MDMA constraints on period maximum size and
      set period maximum to half the buffer maximum size.

      ASoC: max98090: Fix restore of DAPM Muxes · ecb2795c
      Jon Hunter authored
      The max98090 driver defines 3 DAPM muxes; one for the right line output
      (LINMOD Mux), one for the left headphone mixer source (MIXHPLSEL Mux)
      and one for the right headphone mixer source (MIXHPRSEL Mux). The same
      bit is used for the mux as well as the DAPM enable, and although the mux
      can be correctly configured, after playback has completed, the mux will
      be reset during the disable phase. This is preventing the state of these
      muxes from being saved and restored correctly on system reboot. Fix this
      by marking these muxes as SND_SOC_NOPM.
      
      Note this has been verified this on the Tegra124 Nyan Big which features
      the MAX98090 codec.

      ASoC: RT5677-SPI: Disable 16Bit SPI Transfers · a46eb523
      Curtis Malainey authored
      The current algorithm allows 3 types of transfers, 16bit, 32bit and
      burst. According to Realtek, 16bit transfers have a special restriction
      in that it is restricted to the memory region of
      0x18020000 ~ 0x18021000. This region is the memory location of the I2C
      registers. The current algorithm does not uphold this restriction and
      therefore fails to complete writes.
      
      Since this has been broken for some time it likely no one is using it.
      Better to simply disable the 16 bit writes. This will allow users to
      properly load firmware over SPI without data corruption.

      ASoC: sprd: Add reserved DMA memory support · 1587a061
      Baolin Wang authored
      For Spreadtrum audio platform driver, it need allocate a larger DMA buffer
      dynamically to copy audio data between userspace and kernel space, but that
      will increase the risk of memory allocation failure especially the system
      is under heavy load situation.
      
      To make sure the audio can work in this scenario, we usually reserve one
      region of memory to be used as a shared pool of DMA buffers for the
      platform component. So add of_reserved_mem_device_init_by_idx() function
      to initialize the shared pool of DMA buffers to be used by the platform
      component.
