> Doug, how would you feel about reworking the patch that exports > usb_wakeup_enabled_descendants()? Instead of doing it that way, create > and export a new subroutine in hcd.c called > usb_hcd_wakeup_not_needed(), or something similar. We have a use case with another host controller (Tegra, which I think is still in the process of being upstreamed) where we are able to power down PHYs (and thus reduce power consumption) per port. I think we should prefer the more flexible 'number of wake devices in subtree' interface to be able to support cases like that. (And for the simple case, 'if (usb_hcd_wakeup_not_needed(hcd))' and 'if (!usb_wakeup_enabled_descendants(hcd->self.root_hub))' look pretty similar anyway.) -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
