AC97 link bindings
|
|
|
|
These bindings can be included within any other device node.
|
|
|
|
Required properties:
|
|
- pinctrl-names: Has to contain following states to setup the correct
|
|
pinmuxing for the used gpios:
|
|
"ac97-running": AC97-link is active
|
|
"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>;
|
|
|
|
...
|
|
};
