I have sent the pfuze100 regulator patch revert and it is linux-next

That will still break old dtb compatibility.

You cannot force users to use "regulator-always-on" and the old dtbs
need to always work.

So whatever new feature you need to introduce it needs to be done in
such a way that the existing dtb's will continue working.
