I am using https://source.codeaurora.org/external/imx/imx-atf/log/?h=lf_v2.4

Since the driver sending SMCC commands to ATF isn't doing that, I
assume it's safe to use the linux power-domain drivers with the ATF
from NXP's kernel.

If you can point me to the repo you think I should be using, I'll give it a try.
