We can always differentiate later and introduce new compatible.
Declaring a compatible right now would be useful only if we really cared
about using the workaround on older DTBs.

Since I cannot judge the difference (I don't have the datasheet of
S2MPS15) then I don't see the need of adding new compatible/name for the
"same device".

Of course maybe there is such need? Alim?

Best regards,
