We generally use hyphen rather than underscore in node name. Also I
would suggest to have 'led' in the name to tell what the device is,
maybe 'led-green'?

While it's all good to name the node in a general way, the label can be
specific, like:
m25p80: flash@0 {
...
}
Even better, if the label is not really needed, just drop it.

Is the label used at all?
