    7 title: NVIDIA Tegra20 S/PDIF Controller
    8 
    9 description: |
   10   The S/PDIF controller supports both input and output in serial audio
   11   digital interface format. The input controller can digitally recover
   12   a clock from the received stream. The S/PDIF controller is also used
   13   to generate the embedded audio for HDMI output channel.

   53       Specifies whether board prefers parent clock to stay at a fixed rate.
   54       This allows multiple Tegra20 audio components work simultaneously by
   55       limiting number of supportable audio rates.
