+Broadcom Generic Level 2 Interrupt Controller
+
+Required properties:
+
+- compatible: should be one of:
+ "brcm,hif-spi-l2-intc" or
+ "brcm,upg-aux-aon-l2-intc" or
+ "brcm,l2-intc" for latched interrupt controllers
+ should be "brcm,bcm7271-l2-intc" for level interrupt controllers
+- reg: specifies the base physical address and size of the registers
+- interrupt-controller: identifies the node as an interrupt controller
+- #interrupt-cells: specifies the number of cells needed to encode an
+ interrupt source. Should be 1.
+- interrupts: specifies the interrupt line in the interrupt-parent irq space
+ to be used for cascading
+
+Optional properties:
+
+- brcm,irq-can-wake: If present, this means the L2 controller can be used as a
+ wakeup source for system suspend/resume.
+
+Example:
+
+hif_intr2_intc: interrupt-controller@f0441000 {
+ compatible = "brcm,l2-intc";
+ reg = <0xf0441000 0x30>;
+ interrupt-controller;
+ #interrupt-cells = <1>;
+ interrupt-parent = <&intc>;
+ interrupts = <0x0 0x20 0x0>;
+};
