Merge "ARM: tegra: Trusted Foundations work for 3.15" from Stephen Warren:

This pull request contains a number of cleanups and enhancements for the
Trusted Foundations firmware used on production Tegra SoCs. The changes
allow kernels without TF support to run on HW that uses TF, albeit with
reduced functionality, and also fix the cpuidle feature.

* tag 'tegra-for-3.15-tf' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux:
  ARM: tegra: cpuidle: use firmware for power down
  ARM: trusted_foundations: implement prepare_idle()
  ARM: firmware: add prepare_idle() operation
  ARM: firmware: enable Trusted Foundations by default
  ARM: trusted_foundations: fallback when TF support is missing
  ARM: trusted_foundations: fix vendor prefix typos
