Merge branch 'dsa-multi-swtich'
Andrew Lunn says:
====================
D in DSA patches
The D in DSA is distributed, meaning multiple switches can be
connected together. Currently no mainline system does this, and so the
code is broken. This patchset contains two fixes, and a small helper.
With three of more switches, the current device tree binding is not
sufficient to express the routing between the switches. The first
patch extends the binding, in a backwards compatible way, to allow a
link between a switch to describe all the switches accessible over the
link, not just the direct neighbor.
The third patch fixes the port configuration on newer devices for
links connecting switches.
