      ALSA: pci: rme: Fix unaligned buffer addresses · 43d35ccc
      Takashi Iwai authored
      The recent fix for setting up the DMA buffer type on RME drivers tried
      to address the non-standard memory managements and changed the DMA
      buffer information to the standard snd_dma_buffer object that is
      allocated at the probe time.  However, I overlooked that the RME
      drivers handle the buffer addresses based on 64k alignment, and the
      previous conversion broke that silently.
      
      This patch is an attempt to fix the regression.  The snd_dma_buffer
      objects are copied to the original data with the correction to the
      aligned accesses, and those are passed to snd_pcm_set_runtime_buffer()
      helpers instead.  The original snd_dma_buffer objects are managed by
      devres, hence they'll be released automagically.

      ALSA: firewire-motu: add support for MOTU Track 16 · 411ac298
      Takashi Sakamoto authored
      Mark of the Unicorn designed Track 16 2011 as one of models in third
      generation of its FireWire series. The model is already discontinued.
      It consists of below ICs:
      
       * Texas Instruments TSB41AB1
       * Microchip (SMSC) USB3300
       * Xilinx Spartan-3A FPGA, XC3S700A
       * Texas Instruments TMS320C6722
       * Microchip (Atmel) AT91SAM SAM7S512
      
      It supports sampling transfer frequency up to 192.0 kHz. The packet
      format differs depending on both of current sampling transfer frequency
      and the type of signal in optical interfaces. The model supports
      transmission of PCM frames as well as MIDI messages.
      
      The model supports command mechanism to configure internal DSP. Hardware
      meter information is available in the first 2 chunks of each data block
      of tx packet.
      
      This commit adds support for it.
