As per comments in the bindings patch, I think we should move "qcom,drms-mode-max-microamps" to the regulator core.

As per comments in bindings patch: seems like we should get rid of "qcom,regulator-initial-microvolt" or move to the core.

As per comments in other threads, adjust this comment and use -ENOTRECOVERABLE now. NOTE: I think this driver is looking really good now. Hopefully the above things should be quick to spin (even getting "max-microamps" in the core should be quick I think) and we can get something landed! :) -Doug
