I don't understand. If your EHCI controller is connected to three PHYs, how can you avoid powering on all three of them at the same time? If you only powered on some of the PHYs, wouldn't that mean that only some of the ports would work? > This limits us in terms of power management. I would like to patch the ehci driver to accept multiple phys. What is the community's opinion on this ? is there any ongoing work of this nature? You can just submit a patch and see what the response is.
