To follow up from my earlier comment, this .dts structure looks fine
and reasonable to me, and it would also be fine for the mc13892 driver
to use for_each_child_of_node() to find all the children of the
regulators node.  Even finding the 'regulators' node by name from the
mc13892 driver is perfectly fine provided for_each_child_of_node is
used to find it.  All of this is okay because it is under the umbrella
of the "fsl,mc13892" binding.

Yes, a search of children of the device node that the driver is probing
off seems like a sensible approach.
