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. Up to 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 up to 4 interrupt combiners (with each combiner supporting -up to 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.
