The regulator name is "otg-vbus". I would like to get an acked-by from either the regulator framework maintainers, or DT binding maintainers (or both ;)) on the binding. -- Sebastian

Please submit any patches you want reviewing using the process in SubmittingPatches. If this is a regulator driver it should be in drivers/regulator though.

Add a binding for the regulator which controls the OTG chargepath switch. The OTG switch gets its power from pm8941_5vs1, and that should be expressed as a usb_otg_in-supply property in the DT node for the charger driver. The regulator name is "otg-vbus".
