Subject: [RFC 0/3] Portable Device Tree Connector

This patchset introduces a portable device tree based connector.
It allows definition of a connector in a portable format so that
hardware expansion boards that utilize it can use the same
DT hardware definitions unchanged for all the boards that
have the same kind of connector.

It completely abstracts away the baseboard implementation details
and allows one to describe the expansion board in it's isolated
domain without having to figure out the per-board specific
hardware configuration.

The first patchset is the implementation while the next two
define a connector for the beaglebone board.

There was a session at ELC2016 with the slides at
http://elinux.org/images/d/d0/Panto.pdf

This patchset is dependent on the previous two patchset I sent out
some time ago.
