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..
Hmm... Mark Brown (added to Cc) suggested to move this regulator nodes into the board DT file and remove such files [1]. bye, Heiko [1] https://lkml.org/lkml/2015/10/21/581 -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
