Allows the use of pin interrupt and callbacks for pca95xx family
GPIO expander chips with an interrupt line.
Enable config flag and define a gpio pin for the expander interrupt-
line (INT) in devicetree and the driver will accept pin interrupt
configurations for the expander gpio pins.
Level triggering is supported through emulation.
A worker is used to avoid waiting for I2C in ISR.
Example devicetree node:
gpioext0: tca9539@77 {
compatible = "nxp,pca95xx";
label = "GPIO_EXT_0";
reg = <0x77>;
interrupt-gpios = <&gpio1 15 GPIO_ACTIVE_LOW>;
gpio-controller;
#gpio-cells = <2>;
ngpios = <16>;
};
Fixes: #27561
