1 Specifying interrupt information for devices
11 properties contain a list of interrupt specifiers, one per output interrupt. The
12 format of the interrupt specifier is determined by the interrupt controller to
16 interrupt-parent = <&intc1>;
19 The "interrupt-parent" property is used to specify the controller to which
20 interrupts are routed and contains a single phandle referring to the interrupt
22 interrupt client node or in any of its parent nodes. Interrupts listed in the
23 "interrupts" property are always in reference to the node's interrupt parent.
26 to reference multiple interrupt parents or a different interrupt parent than
28 and the interrupt specifier.
39 A device is marked as an interrupt controller with the "interrupt-controller"
40 property. This is a empty, boolean property. An additional "#interrupt-cells"
41 property defines the number of cells needed to specify a single interrupt.
43 It is the responsibility of the interrupt controller's binding to define the
44 length and format of the interrupt specifier. The following two variants are
49 The #interrupt-cells property is set to 1 and the single cell defines the
50 index of the interrupt within the controller.
56 interrupt-controller;
57 #interrupt-cells = <1>;
63 interrupt-controller;
64 #interrupt-cells = <1>;
66 interrupt-parent = <&vic>;
72 The #interrupt-cells property is set to 2 and the first cell defines the
73 index of the interrupt within the controller, while the second cell is used
88 interrupt-parent = <&gpio>;
94 interrupt-controller;
95 #interrupt-cells = <2>;
104 interrupt-parent = <&gpioext>;
121 interrupt-controller;
122 #interrupt-cells = <2>;
