I have sent the pfuze100 regulator patch revert and it is linux-next now. Should probably reach 4.18-rc4.

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.
