2
3Required 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
