-Subject: [PATCH] USB: EHCI: allow limiting ports for ehci-platform
-
-In the same way as the ohci platform driver allows limiting ports,
-enable the same for ehci. This prevents a mismatch in the available
-ports between ehci/ohci on USB 2.0 controllers.
-
-This is needed if the USB host controller always reports the maximum
-number of ports regardless of the number of available ports (because
-one might be set to be usb device).
