Subject: [RFC PATCH 00/16] New DSA bind, switches as devices

This is an RFC patchset and should not be accepted yet.

The interesting patches here are the last three. They implement a new
binding for DSA, which removes a few limitations of the current DSA
binding. In particular, it allows switches to be true Linux devices.
These devices can be on any type of bus, unlike the old DSA binding
which assumes MDIO. See the commit log for more details. The second to
last patch modifies an existing boards device tree to use the new
binding, giving a good example of how switches can be true MDIO
devices. The last patch documents the new binding.

I know both John Crispin and Bryan Whitehead are interesting in
implementing DSA drivers, hence i have CC: you. Comments welcome.

Thanks go to Florian and Vivien for reviewing, testing and bug fixing
these patches.
