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 >;
|
||
|
