      ALSA: asoc: restrict sample rate and size in Freescale MPC8610 sound drivers · be41e941
      Timur Tabi 提交于
      The Freescale MPC8610 SSI device has the option of using one clock for both
      transmit and receive (synchronous mode), or independent clocks (asynchronous).
      The SSI driver, however, programs the SSI into synchronous mode and then
      tries to program the clock registers independently.  The result is that the wrong
      sample size is usually generated during recording.
      
      This patch fixes the discrepancy by restricting the sample rate and sample size
      of the playback and capture streams.  The SSI driver remembers which stream
      is opened first.  When a second stream is opened, that stream is constrained
      to the same sample rate and size as the first stream.
      
      A future version of this driver will lift the sample size restriction.
      Supporting independent sample rates is more difficult, because only certain
      codecs provide dual independent clocks.
