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.
