I think it's best to fix things properly, even if it means that it will take longer and go into next kernel version.

If you're talking about echi wake-up events, I don't see how that would affect core retention.

If you're talking about > echi wake-up events, I don't see how that would affect core retention. Hi Tony the cpu should hit the retention in idle; in this case, up on usb bus suspend ( no device connected) , if I cut the clock, then later device detection happen through I/O wakeup, so implementing the ehci remote wakeup using I/O chain handler ensure the retention in idle too. now, with the existing ehci driver in mainline, whether device connected or not the clocks are not cut and prevents the retention in idle. so, I need to implement the ehci clock gating mechanism through I/O interrupts in bus spend /resume . This activity will take some time. regards keshava -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
