In short adding restrack support to regulators will allow to: - proper handle regulator provider unbind/re-bind, currently it results in oopses, crashes and hangs, - avoid late probe due to deferred probing, currently if probe is deferred, re-probe occurs in late initcall, - track appearance of resources which can alter behavior of the driver if present but they are not required, I am not sure if there are use cases for it in case of regulators, but other resources have such use cases, - as a bonus we can have simpler allocation of various resources, please look at cover letter for example. > > One very high level thing is that anything that only works for DT only > seems to be a non-starter, the API should be hiding details of the > firmware interface. I agree, but as this is RFC, not everything is finished. It seems I have forgotten to mention it clearly in cover letter. Anyway it seems I should adjust patchset and move matching code from restrack/track core to specific frameworks. This way any current or future lookup method should be supported. But the main purpose of this patchset is to get opinions, if the main ideas are OK. And if the patchset can be eventually accepted.
