The tricky bits here will be system suspend/resume support, with the host controller able to trigger remote wakeup. Clearly you don't support system suspend/resume yet. A slightly less tricky bit would be suspending the root hub. Sometimes the hardware needs help there; other times it can automatically gate the various clocks and save power. If you split out patches for each of the drivers, I can ack each of those seaprately. And then hope to see patches which add power management support before too long. - Dave -- 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
