-NVIDIA Tegra 20 AC97 controller
-
-Required properties:
-- compatible : "nvidia,tegra20-ac97"
-- reg : Should contain AC97 controller registers location and length
-- interrupts : Should contain AC97 interrupt
-- resets : Must contain an entry for each entry in reset-names.
-  See ../reset/reset.txt for details.
-- reset-names : Must include the following entries:
-  - ac97
-- dmas : Must contain an entry for each entry in clock-names.
-  See ../dma/dma.txt for details.
-- dma-names : Must include the following entries:
-  - rx
-  - tx
-- clocks : Must contain one entry, for the module clock.
-  See ../clocks/clock-bindings.txt for details.
-- nvidia,codec-reset-gpio : The Tegra GPIO controller's phandle and the number
-  of the GPIO used to reset the external AC97 codec
-- nvidia,codec-sync-gpio : The Tegra GPIO controller's phandle and the number
-  of the GPIO corresponding with the AC97 DAP _FS line
-
-Example:
-
-ac97@...02000 {
-	compatible = "nvidia,tegra20-ac97";
-	reg = <0x70002000 0x200>;
-	interrupts = <0 81 0x04>;
-	nvidia,codec-reset-gpio = <&gpio 170 0>;
-	nvidia,codec-sync-gpio = <&gpio 120 0>;
-	clocks = <&tegra_car 3>;
-	resets = <&tegra_car 3>;
-	reset-names = "ac97";
-	dmas = <&apbdma 12>, <&apbdma 12>;
-	dma-names = "rx", "tx";
-};
