-Sigma Designs SMP86xx/SMP87xx secondary interrupt controller
-
-Required properties:
-- compatible: should be "sigma,smp8642-intc"
-- reg: physical address of MMIO region
-- ranges: address space mapping of child nodes
-- interrupt-controller: boolean
-- #address-cells: should be <1>
-- #size-cells: should be <1>
-
-One child node per control block with properties:
-- reg: address of registers for this control block
-- interrupt-controller: boolean
-- #interrupt-cells: should be <2>, interrupt index and flags per interrupts.txt
-- interrupts: interrupt spec of primary interrupt controller
-
-Example:
-
