+- compatible: "brcm,bcm3384-intc"
+
+ Compatibility with BCM3384 and possibly other BCM33xx/BCM63xx SoCs.
+
+- reg: Address/length pairs for each mask/status register set. Length must
+ be 8. If multiple register sets are specified, the first set will
+ handle IRQ offsets 0..31, the second set 32..63, and so on.
+
+- interrupt-controller: This is an interrupt controller.
+
+- #interrupt-cells: Must be <1>. Just a simple IRQ offset; no level/edge
+ or polarity configuration is possible with this controller.
+
+- interrupt-parent: This controller is cascaded from a MIPS CPU HW IRQ, or

+- interrupts: The IRQ on the parent controller.
