12description: >
13 ARC-HS Interrupt Distribution Unit is an optional 2nd level interrupt
14 controller which can be used in SMP configurations for dynamic IRQ routing,
15 load balancing of common/external IRQs towards core intc.
16
17 The interrupt controller is accessed via the special ARC AUX register
18 interface, hence "reg" property is not specified.

28 Number of interrupt specifier cells:
29 - 1: only a common IRQ is specified.
30 - 2: a second cell encodes trigger type and level flags:
31 1 = low-to-high edge triggered
32 4 = active high level-sensitive (default)
33 enum: [1, 2]
