"ac97-reset": AC97-link reset state
"ac97-warm-reset": AC97-link warm reset state
- ac97-gpios: List of gpio phandles with args in the order ac97-sync,
ac97-sdata, ac97-reset
Example:
ssi {
...
pinctrl-names = "default", "ac97-running", "ac97-reset", "ac97-warm-reset";
pinctrl-0 = <&ac97link_running>;
pinctrl-1 = <&ac97link_running>;
pinctrl-2 = <&ac97link_reset>;
pinctrl-3 = <&ac97link_warm_reset>;
ac97-gpios = <&gpio3 20 0 &gpio3 22 0 &gpio3 28 0>;
...
};
