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.

Search 'in' the parent node or 'from' the parent node?

Where is the property?

Should this be "off"?

The idea was to have the device tree property at the same place for all
twl family devices. 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.

yes, of course.
