+Generic AC97 Device Properties
+
+This documents describes the devicetree bindings for an ac97 controller child
+node describing ac97 codecs.
+
+Required properties:
+-compatible : Must be "ac97,vendor_id1,vendor_id2
+ The ids shall be the 4 characters hexadecimal encoding, such as
+ given by "%04x" formatting of printf
+-reg : Must be the ac97 codec number, between 0 and 3
+
+Example:
+ac97: sound@40500000 {
+ compatible = "marvell,pxa270-ac97";
+ reg = < 0x40500000 0x1000 >;
+ interrupts = <14>;
+ reset-gpios = <&gpio 95 GPIO_ACTIVE_HIGH>;
+ #sound-dai-cells = <1>;
+ pinctrl-names = "default";
+ pinctrl-0 = < &pinctrl_ac97_default >;
+ clocks = <&clks CLK_AC97>, <&clks CLK_AC97CONF>;
+ clock-names = "AC97CLK", "AC97CONFCLK";
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+ audio-codec@0 {
