The interrupt request from each group are connected to16 a parent interrupt controller, such as GIC in case of Exynos4210.17 18 The interrupt combiner controller consists of multiple combiners. Up to eight19 interrupt sources can be connected to a combiner. The combiner outputs one20 combined interrupt for its eight interrupt sources. The combined interrupt is21 usually connected to a parent interrupt controller.22 23 A single node in the device tree is used to describe the interrupt combiner24 controller module (which includes multiple combiners). A combiner in the25 interrupt controller module shares config/control registers with other26 combiners. For example, a 32-bit interrupt enable/disable config register can27 accommodate up to 4 interrupt combiners (with each combiner supporting up to28 8 interrupt sources).29 30allOf:31 - $ref: /schemas/interrupt-controller.yaml#32 33properties:34 compatible:35 const: samsung,exynos4210-combiner36 37 interrupt-controller: true38 39 interrupts:40 minItems: 841 maxItems: 3242 43 "#interrupt-cells":44 description: |45 The meaning of the cells are:46 * First Cell: Combiner Group Number.47 * Second Cell: Interrupt number within the group.48 const: 249 50 reg:51 maxItems: 152 53 samsung,combiner-nr:54 description: |55 The number of interrupt combiners supported.
