[PATCH v2 0/6] ARM: firmware: improvements to Trusted Foundations support

[Alexandre Courbot]

These (mostly minor) patches fix a few typos, improve points that
were agreed upon when the Trusted Foundation series was initially
submitted, and more importantly add support for a prepare_idle()
firmware operation that informs the firmware a CPU is doing idle.
Tegra's cpuidle driver is then also updated accordingly.

These patches should be the last step before device trees for NVIDIA
SHIELD and Tegra Note 7 can be submitted.

Changes since v1:
- Do not remove TF support from tegra_defconfig (will automatically be taken
  care of during next configuration update)
- Add a new prepare_idle() operation to firmware_ops that informs the firmware
  a CPU is going idle (vs. asking the firmware to do it itself as do_idle()
  does)
- Fix idle states names in TF implementation of prepare_idle to sound less
  Tegra-specific

Alexandre Courbot (6):
  ARM: trusted_foundations: fix vendor prefix typos
  ARM: trusted_foundations: fallback when TF support is missing
  ARM: firmware: enable Trusted Foundations by default
  ARM: firmware: add prepare_idle() operation
  ARM: trusted_foundations: implement prepare_idle()
  ARM: tegra: cpuidle: use firmware for power down
