This is an important issue power-wise. Just increasing the polling interval is no optimal solution as we're not solving the biggest issue imho - which is polling. Polling keeps the system out of the deepest possible energy saving states regularly - can't the device fire up an irq or can't this be solved without polling at all ? This goes on once the (device) runtime-PM is used in more and more drivers. It will cause more issues in the long run ... Ideas/Comments ?
