Merge tag 'tegra-soc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/olof/tegra into tegra/soc-drivers

Tegra SoC driver support.

Some device tree conversions, some new drivers. and a fix for an issue
introduced in Grant Likely's irq_domain conversion in his tree. Because
of that, this branch depends on his branch to build (but not to merge):
