Those four 21 families were the only ones to reach the developer and consumer 22 market. 23 24properties: 25 compatible: 26 items: 27 - enum: 28 - intel,ixp42x-interrupt 29 - intel,ixp43x-interrupt 30 - intel,ixp45x-interrupt 31 - intel,ixp46x-interrupt 32 33 reg: 34 maxItems: 1 35 36 interrupt-controller: true 37 38 '#interrupt-cells': 39 const: 2 40 41required: 42 - compatible 43 - reg 44 - interrupt-controller 45 - '#interrupt-cells' 46 47additionalProperties: false 48 49examples: 50 - | 51 intcon: interrupt-controller@c8003000 { 52 compatible = "intel,ixp43x-interrupt"; 53 reg = <0xc8003000 0x100>; 54 interrupt-controller; 55 #interrupt-cells = <2>; 56 };
