So I think this patch looks fine if everyone is agreed that all the
Palmas sub-modules are represented as explicit child nodes in DT, and
the probing of the child nodes is based on the top-level Palmas device
being a bus, and enumerating its children in standard DT style, using
compatible values. (I'm not sure how the child probing/instantiation
will work for non-DT systems though).

I'm not 100% sure if an agreement on the top-level structure of the
Palmas DT bindings was reached though? Can the SlimLogic people confirm
this? I assume Laxman must be OK with it since he's sending this patch?

It might be a good idea to get the final Palmas binding documentation
reviewed and checked in before changing the drivers/.dts files to match
what the final bindings might be.
