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.
