active low signal to the PCA953x.
|
|
- vcc-supply: power supply regulator.

Example:
|
|
|
|
|
|
gpio@20 {
|
|
compatible = "nxp,pca9505";
|
|
reg = <0x20>;
|
|
pinctrl-names = "default";
|
|
pinctrl-0 = <&pinctrl_pca9505>;
|
|
interrupt-parent = <&gpio3>;
|
|
interrupts = <23 IRQ_TYPE_LEVEL_LOW>;
|
|
};
