But I'm getting concerned about this "regulator-always-on" stuff and having multiple copies of the same thing. I think we should have a common am33xx-tps65217.dtsi file that has the regulators defined at one place and other then include it. And they are controllable AFAIK.. Regards, Tony

Hmm it was probably the name of that file causing confusion as it was not am33xx specific. If we have many board variants using almost the same exact regulators and configuration it totally makes sense to have a shared dtsi file for them :) It may actually be better to have it as am33xx-common.dtsi and I bet that covers quite a few am33xx boards for the basic shared functionality.
