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
