Are there any objections to my taking both patches through the Tegra tree? Patch 2/2 depends on 1/2 and is Tegra-specific. This should work out fine unless anyone else wants to use the new header this kernel cycle; if they do, this should go into a topic branch in the DT tree that I can pull into the Tegra tree.
