Thanks for a branch with all the dependencies.

This branch builds & boots, but crashes because in the upstream default
defconfig, the CPUfreq driver is built-in and the regulator that it
depends on is not enabled.

Changing CPUfreq to be modular with CONFIG_ARM_MEDIATEK_CPUFREQ=m
allowed me to boot to a shell on mt8365-evk.

This suggests that this series needs some defconfig patches to enable
the new features, preferably as modules.

It's probably OK that the defconfig patch(es) come as a separate series,
but not sure what Matthias' preferences are here.
