+
+To use GPIO pins as interrupt sources for peripherals, specify the
+GPIO controller as the interrupt parent and define GPIO number +
+trigger mode using the interrupts property, which is defined like
+this:
+
+interrupts = <number trigger>, where:
+ - number: GPIO pin (0..31)
+ - trigger: trigger mode:
+ 2 = trigger on falling edge
+ 3 = trigger on both edges
+
+Example of device using this is:
+
+ funkyfpga@0 {
+ compatible = "funky-fpga";
+ ...
+ interrupts = <4 3>;
+ interrupt-parent = <&gpio1>;
+ };
