Add support for over current protection (OCP), pin control selection, soft start and soft start strength, auto-mode, input current limiting, and pull down.

This can be bool. Unless we want to have a mode property with "auto" being one possible value.

This seems common too.

These 2 are perhaps less common. I hope I don't have a device that does this. :) Rob -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
