* Atmel AC97 controller
Required properties:
- compatible: "atmel,at91sam9263-ac97c"
- reg: Address and length of the register set for the device
- interrupts: Should contain AC97 interrupt
- ac97-gpios: Please refer to soc-ac97link.txt, only ac97-reset is used
Optional properties:
- pinctrl-names, pinctrl-0: Please refer to pinctrl-bindings.txt
Example:
sound@fffa0000 {
compatible = "atmel,at91sam9263-ac97c";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ac97>;
reg = <0xfffa0000 0x4000>;
interrupts = <18 IRQ_TYPE_LEVEL_HIGH 5>;
ac97-gpios = <&pioB 0 0 &pioB 2 0 &pioC 29 GPIO_ACTIVE_LOW>;
};
