I just gave this patch a quick try and things seem to behave for me from PM point of view: Tested-by: Tony Lindgren <tony@xxxxxxxxxxx> Unrelated to this patch, I also noticed that we now somehow higher idle power consumption initially when musb modules are loaded. It used to idle after that but now to get things to idle I had to plug and unplug a USB device once to the musb port.
