What makes you say that we need two properties?

So as well as delaying in the kernel to cover the ramp time you want to
configure something in the PMIC? What are you trying to configure in
the PMIC? How will the PMIC driver meaningfully interpret a generic
property given that the whole point here is that the PMIC is unable to
deliver in spec behaviour?
