that's just interrupt-parent and interrupts in one statement. And since
make dt_binding_check didn't complained I thought that's good this way.
Rob, do I need to describe interrupts-extended as well ?

I could change that to interrupt-parent/interrupts as the driver no
longer uses dma under/overrun interrupts, which have a different
interrupt-parent.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]
