3Required properties:
4- compatible : "nvidia,tegra20-ac97"
5- reg : Should contain AC97 controller registers location and length
6- interrupts : Should contain AC97 interrupt
7- clocks : Must contain one entry, for the module clock.
8  See ../clocks/clock-bindings.txt for details.
9- resets : Must contain an entry for each entry in reset-names.
10  See ../reset/reset.txt for details.
11- reset-names : Must include the following entries:
12  - ac97
13- nvidia,dma-request-selector : The Tegra DMA controller's phandle and
14  request selector for the AC97 controller
15- nvidia,codec-reset-gpio : The Tegra GPIO controller's phandle and the number
16  of the GPIO used to reset the external AC97 codec
17- nvidia,codec-sync-gpio : The Tegra GPIO controller's phandle and the number
18  of the GPIO corresponding with the AC97 DAP _FS line
