"neutron" is not a generic node name. This should be something like "accelerator" or similar.

The only dts nodes I could find using accel subsystem are from rockhip. And they use npu@

e.g:

»       rknn_core_0: npu@fdab0000 { »       »       compatible = "rockchip,rk3588-rknn-core";

Also, Ethos-U64 introduced by Rob with [1] is using npu@.

So, I think we should go wit that. I haven't seen any document to standardize the naming.

accelerator, npu, makes no difference to me, so sure.
