I haven't heard any reason yet to convert them to runtime PM - they don't even make any runtime PM calls. Maybe Linus can comment on the PM stuff as he has SoCs with these in. As my boards don't have any sensible PM support, I don't have any visibility of what PM facilities would be required. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
