-Subject: [PATCH 20/26] USB: Add driver for the ssb bus
-
-This adds a USB driver using the generic platform device driver for the
-USB controller found on the Broadcom ssb bus. The ssb bus just
-exposes one device which serves the OHCI and the EHCI controller at the
-same time. This driver probes for this USB controller and creates and
-registers two new platform devices which will be probed by the new
-generic platform device driver. This makes it possible to use the EHCI
-and the OCHI controller on the ssb bus at the same time.
-
-The old ssb OHCI USB driver will be removed in the next step as this
-driver also provide an OHCI driver and an EHCI for the cores supporting
-it.
