This suggests the single multiplexed interrupt on R-Car Gen2 can be called
"ch0". Is that what you want? I know the driver doesn't care.

No, its not what I intended.

I think its reasonable to allow the multiplexed interrupt to be named,
but to what I wonder. The documentation seems to call the interrupt
"EthernetAVB", which isn't very exciting.

Perhaps "mux", like I did for rspi, cfr.

                       If interrupt-names is not present, an interrupt specifier

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
