[PATCH v2 0/6] ARM: firmware: improvements to Trusted Foundations support
From: Alexandre Courbot
Date: Thu Feb 06 2014 - 23:35:47 EST
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
