It performs +one-to-one mapping of external interrupt sources to CPU interrupts and +provides support for reconfigurable trigger modes. + +Required properties +------------------- + +- compatible: Should be "abilis,tb10x-ictl" +- reg: specifies physical base address and size of register range. +- interrupt-congroller: Identifies the node as an interrupt controller. +- #interrupt cells: Specifies the number of cells used to encode an interrupt + source connected to this controller. The value shall be 2. +- interrupt-parent: Specifies the parent interrupt controller. +- interrupts: Specifies the list of interrupt lines which are handled by + the interrupt controller in the parent controller's notation. Interrupts + are mapped one-to-one to parent interrupts. + +Example +------- + +intc: interrupt-controller { /* Parent interrupt controller */ + interrupt-controller; + #interrupt-cells = <1>; /* For example below */ + /* ... */ +}; + +tb10x_ictl: pic@2000 { /* TB10x interrupt controller */ + compatible = "abilis,tb10x-ictl"; + reg = <0x2000 0x20>; + interrupt-controller; + #interrupt-cells = <2>; + interrupt-parent = <&intc>; + interrupts = <5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 + 20 21 22 23 24 25 26 27 28 29 30 31>; +}; |
