I'd rather like to get rid of CONFIG_TEGRA_xx_SOC and replace it with 
CONFIG_TEGRA, but I suppose that idea wasn't received well. So,

I assume this will be applied to the arm-soc tree, although 
arm at kernel.org wasn't CC'd?

I would expect the opposite. Most new DTs are likely to be for the most 
recent SoC, and hence this will concentrate the edits into a smaller 
part of the file and cause more merge conflicts. That is, if the changes 
are going through different trees, which they should not be, which makes 
merge conflicts less relevant.
