This patch series improves the watchdog driver used on the Broadcom
bcm47xx SoCs.
The watchdog driver does not access the functions directly any more,
but it registers as a platform device driver and ssb and bcma are
registering a device for this watchdog driver.
This also adds support for SoCs with a power management unit (PMU),
which have different clock rates.
This code is currently based on the wireless-testing/master tree by
John Linville, because there are some changes in ssb and bcma in that
tree queued for 3.8 which will conflict with these changes, if this
would be based on an other tree. I have no problem with rebasing this
onto any other tree.
@Wim Could you give me an ACK on the "watchdog: bcm47xx_wdt.c:" patches
so that John could take them trough the wireless-testing tree, or
provide me with some feedback on what I should change.
v2:
* reword some commit messages
* rebase on current wireless-testing/master with
"ssb: extif: fix compile errors" applied on top of it.
* do not change value of WDT_SOFTTIMER_MAX
* moved some small changes in the bcm47xx_wdt.c patches
