3Required properties:
4
Alexander Shiyan4b4d9942016-06-04 10:09:56 +03005- compatible: Should be "cirrus,ep7209-intc".
Alexander Shiyanbaee2142014-02-02 12:08:40 +04006- reg: Specifies base physical address of the registers set.
7- interrupt-controller: Identifies the node as an interrupt controller.
8- #interrupt-cells: Specifies the number of cells needed to encode an
9 interrupt source. The value shall be 1.
