-Subject: [PATCH 18/21] USB: EHCI: Add a generic platform device driver
-
-This adds a generic driver for platform devices. It works like the PCI
-driver and is based on it. This is for devices which do not have an own
-bus but their EHCI controller works like a PCI controller. It will be
-used for the Broadcom bcma and ssb USB EHCI controller.
