Briefly tested on a SDM632+PMI632-based Fairphone 3.
I didn't really check for vibration strength or anything more detailed
but with the fftest tool the vibrator seems to work fine!
Diff is attached below. I can send the pmi632.dtsi change once this
series is merged (unless you send something first).
Many thanks for sending these patches!
