It was several releases ago it got broken, exactly which one I can't
really tell.

I suspect this also is related to an upgrade of the boot loader, as in
the earlier version of the series there where a pmic clock driver
included, however it got picked up for 4.12.

Looping in Daniel, just to see if he have some comments on this.

No matter what, I still think it makes sense to pick this for 4.12
rcs, because it also simplifies for us for how to deal with the
mmc+arm64 dependency, since this needs to go together (to avoid
damaging the WiFi chip when power off)

Apologize about that! I will make that clear, if/when next time!
