Sure, seems quite straight forward to add DT support for those
too. I just based my patches on top of whats already in -next and
some changes from Tero. Did not notice there are more patches floating
around touching twl-regulator :)
Depending on what order Mark happens to pull them in, I am fine
re-sending adding support for the 2 twl6030 fixed regulators.
