Hauke Mehrtens bde327eff8 ssb: register watchdog driver
Register the watchdog driver to the system if it is a SoC. Using the
watchdog on a non SoC device, like a PCI card, will make the PCI
card die when the timeout expired, but starting it again is not
supported by ssb.

Hauke Mehrtens 9f640a6376 ssb: extif: add methods for watchdog driver
The watchdog driver wants to set the watchdog timeout in ms and not in
ticks, add a method converting ms to ticks before setting the watchdog
register. Return the ticks or millisecond the timer was set to in case
the provided value was bigger than the max allowed value.

Hauke Mehrtens 7ffbffe37d ssb: add methods for watchdog driver
The watchdog driver wants to set the watchdog timeout in ms and not in
ticks, which is depending on the SoC type and the clock.
Calculate the number of ticks per millisecond and provide two functions
for the watchdog driver. Also return the ticks or millisecond the timer
was set to in case the provided value was bigger than the max allowed
value.

Hauke Mehrtens f924e1e989 ssb: get alp clock from devices with PMU
If there is a PMU in the device, get the alp clock from that part and
do not assume 20000000.

Hauke Mehrtens b3ae52b6b0 SSB: Change fallback sprom to callback mechanism.
Some embedded devices like the Netgear WNDR3300 have two SSB based cards
without an own sprom on the pci bus. We have to provide two different
fallback sproms for these and this was not possible with the old solution.
In the bcm47xx architecture the sprom data is stored in the nvram in the
main flash storage. The architecture code will be able to fill the sprom
with the stored data based on the bus where the device was found.

The bcm63xx code should do the same thing as before, just using the new
API.

Michael Buesch 3ba6018aa3 ssb: Fix SPROM writing
The SPROM writing routines were broken since we rewrote the suspend
handling on wireless devices, because SPROM writing depended on suspend.

This patch changes it and freezes devices with the driver remove(), probe()
callbacks instead. This also simplifies the whole logics a lot.

Albert Herranz 24ea602e18 ssb: Implement SDIO host bus support
Add support for communicating with a Sonics Silicon Backplane through a
SDIO interface, as found in the Nintendo Wii WLAN daughter card.

The Nintendo Wii WLAN card includes a custom Broadcom 4318 chip with
a SDIO host interface.

Michael Buesch e79c1ba84c ssb: Add SPROM fallback support
This adds SSB functionality to register a fallback SPROM image from the
architecture setup code.

Weird architectures exist that have half-assed SSB devices without SPROM attached to
their PCI busses. The architecture can register a fallback SPROM image that is
used if no SPROM is found on the SSB device.

Michael Buesch 8fe2b65a18 ssb: Turn suspend/resume upside down
Turn the SSB bus suspend mechanism upside down.
Instead of deciding by an internal reference count when to suspend/resume,
let the parent bus call us in their suspend/resume routine.

Alexey Zaytsev c7084535c9 Use a separate config option for the b43 pci to ssb bridge.
The bridge code was unnecessary enabled by the b44
driver, but it prevents the bcm43xx driver from
being loaded, as the bridge claims the same pci ids.

Now we enable the birdge only if the b43{legacy}
drivers are selected.

Michael Buesch 61e115a56d [SSB]: add Sonics Silicon Backplane bus support
SSB is an SoC bus used in a number of embedded devices.  The most
well-known of these devices is probably the Linksys WRT54G, but there
are others as well.  The bus is also used internally on the BCM43xx
and BCM44xx devices from Broadcom.

This patch also includes support for SSB ID tables in modules, so
that SSB drivers can be loaded automatically.
