Allwinner Sunxi Interrupt Controller
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
|
||
|
|
- compatible : should be "allwinner,sun4i-ic"
|
||
|
|
- reg : Specifies 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. The value shall be 1.
|
||
|
|
|
||
|
|
