-Subject: [PATCH 01/47] USB: OHCI: 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 OHCI controller works like a PCI controller. It will be
-used for the Broadcom bcma and ssb USB OHCI controller.
