| - 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>;
| gpio-line-names =
| "hdmi-ct-hpd", "hdmi.ls-oe", "p02", "p03", "vibra", "fault2", "p06", "p07",
| "en-usb", "en-host1", "en-host2", "chg-int", "p14", "p15", "mic-int", "en-modem",
| "shdn-hs-amp", "chg-status+red", "green", "blue", "en-esata", "fault1", "p26", "p27";
| };
|
| ts3a227@3b {
| compatible = "ti,ts3a227e";
| reg = <0x3b>;
| interrupt-parent = <&gpio99>;
| interrupts = <14 IRQ_TYPE_EDGE_RISING>;
| ti,micbias = <0>; /* 2.1V */
| };
