* Marvell Orion Interrupt controller
Required properties
- compatible : Should be "marvell,orion-intc".
- #interrupt-cells: Specifies the number of cells needed to encode an
interrupt source. Supported value is <1>.
- interrupt-controller : Declare this node to be an interrupt controller.
- reg : Interrupt mask address. A list of 4 byte ranges, one per controller.
One entry in the list represents 32 interrupts.
Example:
intc: interrupt-controller {
compatible = "marvell,orion-intc", "marvell,intc";
interrupt-controller;
#interrupt-cells = <1>;
reg = <0xfed20204 0x04>,
