    You use this prop, yet don't describe it?

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.

What's korina?

In any case, just drop as it is redundant.

Just rx and tx.

No, the tooling handles both cases. What the parent is is outside the 
scope of a binding.

Humm, you should be describing the interrupt connections the h/w block 
has, not what the driver uses (today) or not.

    I know. :-) Yet you don't mention it, making the "interrupts" prop 
mandatory instead. And as both interrupt parents are the same here, it does 
not even seem justified...

    In DT, we describe the hardware,  not the driver's capabilities.
