Optional properties:
- reset-gpios: GPIO specification for the RESET input. This is an
active low signal to the PCA953x.
Example:
gpio@20 {
compatible = "nxp,pca9505";
reg = <0x20>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_pca9505>;
interrupt-parent = <&gpio3>;
interrupts = <23 IRQ_TYPE_LEVEL_LOW>;
};
