0001 Cirrus Logic CLPS711X Interrupt Controller
0002
0003 Required properties:
0004
0005 - compatible: Should be "cirrus,ep7209-intc".
0006 - reg: Specifies base physical address of the registers set.
0007 - interrupt-controller: Identifies the node as an interrupt controller.
0008 - #interrupt-cells: Specifies the number of cells needed to encode an
0009 interrupt source. The value shall be 1.
