-Subject: [PATCH 15/21] bcma: scan for extra address space
-
-Some cores like the USB core have two address spaces. In the USB host
-controller one address space is used for the OHCI and the other for the
-EHCI controller interface. The USB controller is the only core I found
-with two address spaces. This code is based on the AI scan function
-ai_scan() in shared/aiutils.c i the Broadcom SDK.

-Subject: [PATCH 19/30] USB: Add driver for the bcma bus
-
-This adds a USB driver using the generic platform device driver for the
-USB controller found on the Broadcom bcma bus. The bcma 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 bcma bus at the same time.

+
+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.

+
+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.

+
+Some cores like the USB core have two address spaces. In the USB host

+EHCI controller interface. The USB controller is the only core I found
+with two address spaces. This code is based on the AI scan function
+ai_scan() in shared/aiutils.c i the Broadcom SDK.

+
+This adds a USB driver using the generic platform device driver for the
+USB controller found on the Broadcom bcma bus. The bcma 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 bcma bus at the same time.

+Subject: [PATCH 185/186] 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.
