| 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"; |
| } |
| }; |
