[alsa-devel] [RFC v2 0/6] sti: add audio interface to the hdmi driver

[Arnaud Pouliquen]

V2:
     - patch: ALSA: pcm: add IEC958 channel status control helper
          - Return 1 instead of 0 in snd_pcm_iec958_put
          - Add .access field in control structure
          - I have kept condition on mutex for flexibility 
            (but could be cleaned to force user to use a mutex)
     - patch: video: hdmi: add helper function for N and CTS
         - Duplicate function to have a separte treatment for coherent and
           non-coherent clcocks
         - Add ratio fiel for alternate CTS value
         - Clock frequency in Hz for TMDS and audio clocks
         - Add information concerning clocks and CTS calculation.
