interrupts would work just fine here:

interrupts = <GIC_SPI 4 IRQ_TYPE_LEVEL_HIGH>,
  <GIC_SPI 5 IRQ_TYPE_LEVEL_HIGH>,
  <GIC_SPI 6 IRQ_TYPE_LEVEL_HIGH>,
  <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>,
  <GIC_SPI 8 IRQ_TYPE_LEVEL_HIGH>,
  <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>,
  <GIC_SPI 10 IRQ_TYPE_LEVEL_HIGH>,
  <GIC_SPI 11 IRQ_TYPE_LEVEL_HIGH>;

We don't need a different solution for N:1 interrupts from N:M. Sure,
that could become unweldy if there are a lot of interrupts (just like
interrupt-map), but is that an immediate problem?

It's just that with this approach the driver will have to index the
interrupts instead of reading from DT.

Marc - is it OK with the above approach?

Anything that uses standard properties in a standard way works for me.
