ARC-HS Interrupt Distribution Unit is an optional 2nd level interrupt
|
|
controller which can be used in SMP configurations for dynamic IRQ routing,
|
|
load balancing of common/external IRQs towards core intc.
|
|
|
|
The interrupt controller is accessed via the special ARC AUX register
|
|
interface, hence "reg" property is not specified.

Number of interrupt specifier cells:
|
|
- 1: only a common IRQ is specified.
|
|
- 2: a second cell encodes trigger type and level flags:
|
|
1 = low-to-high edge triggered
|
|
4 = active high level-sensitive (default)
|
|
enum: [1, 2]
