1 * Samsung Exynos Interrupt Combiner Controller
3 Samsung's Exynos4 architecture includes a interrupt combiner controller which
4 can combine interrupt sources as a group and provide a single interrupt request
5 for the group. The interrupt request from each group are connected to a parent
6 interrupt controller, such as GIC in case of Exynos4210.
8 The interrupt combiner controller consists of multiple combiners. Up to eight
9 interrupt sources can be connected to a combiner. The combiner outputs one
10 combined interrupt for its eight interrupt sources. The combined interrupt
11 is usually connected to a parent interrupt controller.
13 A single node in the device tree is used to describe the interrupt combiner
14 controller module (which includes multiple combiners). A combiner in the
15 interrupt controller module shares config/control registers with other
16 combiners. For example, a 32-bit interrupt enable/disable config register
17 can accommodate up to 4 interrupt combiners (with each combiner supporting
18 up to 8 interrupt sources).
21 - compatible: should be "samsung,exynos4210-combiner".
22 - interrupt-controller: Identifies the node as an interrupt controller.
23 - #interrupt-cells: should be <2>. The meaning of the cells are
25 * Second Cell: Interrupt number within the group.
26 - reg: Base address and size of interrupt combiner registers.
27 - interrupts: The list of interrupts generated by the combiners which are then
28 connected to a parent interrupt controller. The format of the interrupt
29 specifier depends in the interrupt parent controller.
32 - samsung,combiner-nr: The number of interrupt combiners supported. If this
41 combiner:interrupt-controller@10440000 {
42 compatible = "samsung,exynos4210-combiner";
43 interrupt-controller;
44 #interrupt-cells = <2>;
