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.

 * 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

Hauke Mehrtens (15):
  watchdog: bcm47xx_wdt.c: convert to watchdog core api
  watchdog: bcm47xx_wdt.c: use platform device
  watchdog: bcm47xx_wdt.c: rename ops methods
  watchdog: bcm47xx_wdt.c: rename wdt_time to timeout
  watchdog: bcm47xx_wdt.c: add hard timer
  bcma: add bcma_chipco_alp_clock
  bcma: set the pmu watchdog if available
  bcma: add methods for watchdog driver
  bcma: register watchdog driver
  ssb: get alp clock from devices with PMU
  ssb: set the PMU watchdog if available
  ssb: add methods for watchdog driver
  ssb: extif: add check for max value before setting watchdog register
  ssb: extif: add methods for watchdog driver
  ssb: register watchdog driver
