+TI LP3943 MFD driver

This is a Linuxism. Use ../bindings/.. instead.
Okay.
+Example:
+
+lp8733: lp8733@60 {
lp8733 is not a device 'type'. What does it do?
Looks like a 'pmic' to me.

I'm failing to see how this is an MFD?
As of now, only regulators part is supported, there are Configurable
General Purpose Output Signals (GPO), Over-Temperature Warning and
Protection apart from regulators.
