Merge tag 'tegra-for-3.20-arm64' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/arm64

Merge "arm64: Add initial Tegra support" from Thierry Reding:

This adds support for the Tegra132 SoC, which is essentially a Tegra124
with a dual Denver CPU complex instead of the quad-Cortex-A15. There is
not much here, only the Kconfig entries, but it will allow us to more
easily get subsequent patches in (many of which have already been sent
for review).

* tag 'tegra-for-3.20-arm64' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux:
  arm64: Add Tegra132 support
  soc: tegra: Add thermal reset (thermtrip) support to PMC
  ARM: tegra: Add PMC thermtrip programming to Jetson TK1 device tree
  of: Add descriptions of thermtrip properties to Tegra PMC bindings
  soc/tegra: pmc: Add Tegra132 support
  soc/tegra: fuse: Add Tegra132 support
  soc/tegra: fuse: Constify tegra_fuse_info structures
  soc/tegra: Add Tegra132 support
  clocksource: Build Tegra timer on 32-bit ARM only
  soc/tegra: pmc: restrict compilation of suspend-related support to ARM
