Hi Mark,

Thanks for catching this!

After browsing through the provided logs it would seem like no device under the
AIPSTZ bus gets probed. Right now, my guess is that the AIPSTZ driver is not being
compiled since CONFIG_IMX_AIPSTZ might be set to 'n'.

Which defconfig is the CI using? Is it arch/arm64/configs/defconfig?

Thanks,
Laurentiu
