The i.MX 8MP has a ADC_PD bit in the TMU_TER register that controls
the
operating mode of the ADC:
* 0 means normal operating mode
* 1 means power down mode

When enabling/disabling the TMU, the ADC operating mode must be set
accordingly.

i.MX 8M Mini & Nano are lacking this bit.

Often this bit is set already by the bootloader, but in case this
is not
done, the file /sys/class/thermal/thermal_zone0/temp will always
return
-EAGAIN.

Does it deserve a Fixes tag?

The more I think about it, the more I'm inclined to add one.
Please tell me if I shall iterate v2 adding a Fixes tag (or other
changes)

Best regards,
Alexander
