- gpio-controller: if used as gpio expander.
|
||||
- #gpio-cells: if used as gpio expander.
|
||||
- interrupt-controller: if to be used as interrupt expander.
|
||||
- #interrupt-cells: if to be used as interrupt expander.
|
||||
|
||||
Optional properties:
|
||||
- interrupts: interrupt specifier for the device's interrupt output.
|
||||
- reset-gpios: GPIO specification for the RESET input. This is an
|
||||
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>;
|
||||
};
|
||||
|
||||
|
||||
Example with Interrupts:
|
||||
|
||||
|
||||
gpio99: gpio@22 {
|
||||
compatible = "nxp,pcal6524";
|
||||
reg = <0x22>;
|
||||
interrupt-parent = <&gpio6>;
|
||||
interrupts = <1 IRQ_TYPE_EDGE_FALLING>; /* gpio6_161 */
|
||||
interrupt-controller;
|

#interrupt-cells = <2>;
|
||||
vcc-supply = <&vdds_1v8_main>;
