Merge tag 'tegra-for-3.13-deps-for-arm-init-time-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into clk-of-init-v2_for-3.13

ARM: tegra: dependencies for ARM .init_time cleanup

This patch is a dependency for Sebastian Hesselbarth's series that
cleans up the ARM machine descriptor's .init_time hook. It may also end
up being a dependency for cleanup/development in the Tegra tree, and
hence is contained in its own topic branch, to allow conflicts to be
easily resolved.
