The BCM7038 L1 interrupt controller can be used as a wake-up interrupt

- interrupts: specifies the interrupt line(s) in the interrupt-parent controller
node; valid values depend on the type of parent interrupt controller
Optional properties:
- brcm,irq-can-wake: If present, this means the L1 controller can be used as a
wakeup source for system suspend/resume.
If multiple reg ranges and interrupt-parent entries are present on an SMP
system, the driver will allow IRQ SMP affinity to be set up through the
/proc/irq/ interface. In the simplest possible configuration, only one
