hmm, it looks like all the others below are named key-power, while
only this uses power-key ?

The naming actually carries over from the device itself.
In the schematics the relevant keys are also named sw1, sw2, etc.
And I do believe it is way nicer when devicetree names correspond to the
things you find in device schematics and not be named "arbitarily" to
only conform to some schema ;-)
So personally I'd actually prefer going with switch-sw1 (or button-sw1 if
you prefer) as being able to just use the search function in schematic pdfs
is a helpful tool.
