Pasting the patch into a mail after some other text definitely doesn't give a mail in the format covered in SubmittingPatches. If in doubt send the mail to yourself and then compare it with other patches sent to the list and test by applying with git am and make sure the patch and changelog come out OK. > +- regulator-valid-modes-mask: valid operations for regulator on particular machine This is not adequately documented, what are "valid operations" and how would they be encoded? > +- regulator-input-uv: regulator input voltage, only if supply is another regulator Why provide a property for this, surely if there is another regulator we can just find out from that regulator what voltage it is outputting? > +- regulator-initial-mode: default mode to set on startup It is not documented what a mode is here or how one would specify it in the property. > +- regulator-initial-state: suspend state to set at init Again, no semantics are provided for this. > +- regulator-state-mem, regulator-state-disk, regulator-state-standby: > + defines regulator suspend to memory, suspend to disk (hibernate) and standby respectively. > + have following sub-constarints: > + - regulator-state-uv: suspend voltage > + - regulator-state-mode: suspend regulator operating mode > + - regulator-state-enabled: is regulator enabled in this suspend state > + - regulator-state-disabled: is the regulator disbled in this suspend state I am very nervous about the idea of putting this stuff into DT. This matches less and less well with modern system designs which are becoming more and more dynamic, and of course the concepts of suspending to memory, disk and standby are unclear and fluid - what is the difference between memory and standby for example? I'd be interested to know if there are real systems that need this and can't figure out what to do dynamically.
