| - 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>; |
| gpio-controller; |
| #gpio-cells = <2>; |
| 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>; |
| gpio-controller; |
| #gpio-cells = <2>; |
