Great, thanks! Are you planning a DM pull request soon? There are some 
patches there which are a dependency for the T186 support I sent out, 
and I believe that all the dependencies are applied there, so a pull 
request (once applied by TomR) would be enough for TomW to apply all the 
Tegra patches.
