     12description: |
     13  Samsung's Exynos4 architecture includes a interrupt combiner controller which
     14  can combine interrupt sources as a group and provide a single interrupt
     15  request for the group. The interrupt request from each group are connected to
     16  a parent interrupt controller, such as GIC in case of Exynos4210.
     17
     18  The interrupt combiner controller consists of multiple combiners. Up to eight
     19  interrupt sources can be connected to a combiner. The combiner outputs one
     20  combined interrupt for its eight interrupt sources. The combined interrupt is
     21  usually connected to a parent interrupt controller.
     22
     23  A single node in the device tree is used to describe the interrupt combiner
     24  controller module (which includes multiple combiners). A combiner in the
     25  interrupt controller module shares config/control registers with other
     26  combiners. For example, a 32-bit interrupt enable/disable config register can
     27  accommodate up to 4 interrupt combiners (with each combiner supporting up to
     28  8 interrupt sources).
