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.
Documentation/devicetree/bindings/spi/spi-rspi.txt:

  - interrupts       : A list of interrupt-specifiers, one for each entry in
                       interrupt-names.
                       If interrupt-names is not present, an interrupt specifier
                       for a single muxed interrupt.
  - interrupt-names  : A list of interrupt names. Should contain (if present):
                         - "error" for SPEI,
                         - "rx" for SPRI,
                         - "tx" to SPTI,
                         - "mux" for a single muxed interrupt.

Thanks for for that example. "mux" sounds good to me.
