To me this continues to be a bit illdefined. Say we have three states: 0,1,2. State 0 is the idle_standby. Providing a minimum residency for state 1 compared to state 0 sort of makes sense, but if we provide a minimum residency for state 2 compared to state 0 the break even time is going to be smaller than break even when comparing state 1 and state 2. With this data we'd enter state 2 when we'd be better off entering state 1. --Antti -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
