-* Samsung Exynos Interrupt Combiner Controller
-
-Samsung's Exynos4 architecture includes a interrupt combiner controller which
-can combine interrupt sources as a group and provide a single interrupt request
-for the group. The interrupt request from each group are connected to a parent
-interrupt controller, such as GIC in case of Exynos4210.
-
-The interrupt combiner controller consists of multiple combiners. Upto eight
-interrupt sources can be connected to a combiner. The combiner outputs one
-combined interrupt for its eight interrupt sources. The combined interrupt
-is usually connected to a parent interrupt controller.
-
-A single node in the device tree is used to describe the interrupt combiner
-controller module (which includes multiple combiners). A combiner in the
-interrupt controller module shares config/control registers with other
-combiners. For example, a 32-bit interrupt enable/disable config register
-can accommodate upto 4 interrupt combiners (with each combiner supporting
-upto 8 interrupt sources).
-
-Required properties:
-- compatible: should be "samsung,exynos4210-combiner".
-- interrupt-controller: Identifies the node as an interrupt controller.
-- #interrupt-cells: should be <2>. The meaning of the cells are
- * First Cell: Combiner Group Number.
- * Second Cell: Interrupt number within the group.
-- reg: Base address and size of interrupt combiner registers.
-- interrupts: The list of interrupts generated by the combiners which are then
- connected to a parent interrupt controller. The format of the interrupt
- specifier depends in the interrupt parent controller.
-
-Optional properties:
-- samsung,combiner-nr: The number of interrupt combiners supported. If this
- property is not specified, the default number of combiners is assumed
- to be 16.
-- interrupt-parent: pHandle of the parent interrupt controller, if not
- inherited from the parent node.
-
-
-Example:
-
- The following is a an example from the Exynos4210 SoC dtsi file.
-
- combiner:interrupt-controller@10440000 {
- compatible = "samsung,exynos4210-combiner";
- interrupt-controller;
- #interrupt-cells = <2>;
- reg = <0x10440000 0x1000>;
- interrupts = <0 0 0>, <0 1 0>, <0 2 0>, <0 3 0>,
- <0 4 0>, <0 5 0>, <0 6 0>, <0 7 0>,
- <0 8 0>, <0 9 0>, <0 10 0>, <0 11 0>,
- <0 12 0>, <0 13 0>, <0 14 0>, <0 15 0>;
- };
