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 {
reg = <0>;
compatible = "ac97,574d,4c13";
clocks = <&fixed_wm9713_clock>;
clock-names = "ac97_clk";
}
};
