1 Cirrus Logic CLPS711X Interrupt Controller
2
3 Required properties:
4
5 - compatible: Should be "cirrus,ep7209-intc".
6 - 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.
