Subject: [PATCH 08/26] bcm47xx: prepare to support different buses
|
||||
|
||||
Prepare bcm47xx to support different System buses. Before adding
|
||||
support for bcma it should be possible to build bcm47xx without the
|
||||
need of ssb. With this patch bcm47xx does not directly contain a
|
||||
ssb_bus, but a union contain all the supported system buses. As a SoC
|
||||
just uses one system bus a union is a good choice.

||||

Subject: [PATCH 10/26] bcm47xx: add support for bcma bus
|
||||
|
||||
This patch add support for the bcma bus. Broadcom uses only Mips 74K
|
||||
CPUs on the new SoC and on the old ons using ssb bus there are no Mips
|
||||
74K CPUs.

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.

It is used in bcma_core_set_clockmode() and bcma_core_pll_ctl() to

Subject: [PATCH 17/21] 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.

Subject: [PATCH 19/26] 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.

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.
