1* Cavium Interrupt Bus widget 2 3Properties: 4- compatible: "cavium,octeon-7130-cib" 5 6 Compatibility with cn70XX SoCs. 7 8- interrupt-controller: This is an interrupt controller. 9 10- reg: Two elements consisting of the addresses of the RAW and EN 11 registers of the CIB block 12 13- cavium,max-bits: The index (zero based) of the highest numbered bit 14 in the CIB block. 15 16- interrupts: The CIU line to which the CIB block is connected. 17 18- #interrupt-cells: Must be <2>. The first cell is the bit within the 19 CIB. The second cell specifies the triggering semantics of the 20 line. 21 22Example: 23 24 interrupt-controller@107000000e000 { 25 compatible = "cavium,octeon-7130-cib"; 26 reg = <0x10700 0x0000e000 0x0 0x8>, /* RAW */ 27 <0x10700 0x0000e100 0x0 0x8>; /* EN */ 28 cavium,max-bits = <23>; 29 30 interrupt-controller; 31 interrupt-parent = <&ciu>; 32 interrupts = <1 24>; 33 /* Interrupts are specified by two parts: 34 * 1) Bit number in the CIB* registers 35 * 2) Triggering (1 - edge rising 36 * 2 - edge falling 37 * 4 - level active high 38 * 8 - level active low) 39 */ 40 #interrupt-cells = <2>; 41 }; 42
