Hi Simon,

These irqs are described in [0] (wlan irq line*). They are the irq lines fired
by the NPU when the wlan traffic is not hw accelerated. These interrupts will
be consumed by the MT76 driver (I will post the MT76 patches in the near future).
I will improve the commit message in v2.

Regards,
Lorenzo
