This is exactly what I had to revert (as I mentioned in the other email,
I had to revert the other patches otherwise compilation would break):

0e8e5c34 "regulator: twl: Remove references to 32kHz clock from DT bindings"
e76ab829 "regulator: twl: Remove references to the twl4030 regulator"
029dd3ce "regulator: twl: Remove another unused variable warning"

Let me know if you need more info.
