   2
   3 Required properties:
   4 - compatible : "nvidia,tegra20-ac97"
   5 - reg : Should contain AC97 controller registers location and length
   6 - interrupts : Should contain AC97 interrupt
   7 - nvidia,dma-request-selector : The Tegra DMA controller's phandle and
   8   request selector for the AC97 controller
   9 - nvidia,codec-reset-gpio : The Tegra GPIO controller's phandle and the number
  10   of the GPIO used to reset the external AC97 codec
  11 - nvidia,codec-sync-gpio : The Tegra GPIO controller's phandle and the number
  12   of the GPIO corresponding with the AC97 DAP _FS line
  13 Example:
