Laxman,

Don't we need to resolve and agree on the final DT bindings before we
can start making changes like this? It's not clear yet whether everyone
is on the same page re: how the MFD sub-devices are modelled in DT -
whether each sub-component really is a standalone device, or whether the
MFD itself instantiates all its children based on internal static tables
rather than DT.

Presumably, the answer to that question directly determines whether the
code change above is correct; the correct of_node might be either the
main Palmas node (if DT doesn't represent the MFD components) or it
might be the regulator sub-node (if DT is used to represent MFD components).

Given that, I'm not sure why the Slimlogic people aren't CC'd on this
patch:-(
