So no distinction for these devices needed in the bindings. It is in the main node. I guess today this twl4030-power subnode would not be accepted nowadays and the compatible would be some kind of flag in the parent. > > for the tag.

Instead of only accepting the ti specific properties accept also the standard property. For uniformity, search in the parent node for the tag. The code for powering of is also isolated from the rest in this file. So it is a pure Linux design decision to put it here.
