Should the processor group > membership be set only once during init? I think it should certainly be set during init. The PM scripts don't change membership, but I can imagine some of them would want to use custom type or subtype codes that would also need to be set during init. The current way to enable/disable a regulator for Linux purposes is to add/remove it from the P1 group. That seems OK for now... only a handful of regulators use software control like that, which would change membership after init. But we *could* enable/disable by directly setting the mode. I decided against doing it that way, on the grounds that until we get some use cases that need something else, we're best off keeping things simple. - Dave -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
