    Wim, while at it, here's a related omap_wdt question:

    Some omap devices like Nokia 770, N800 and N810 have also a secondary
    watchdog on the retu chip connected via cbus. This watchdog needs
    to be kicked as it cannot be disabled.

    We've been thinking of adding a function that omap_wdt can
    call to also kick retu_wdt too as there is only one wdt interface.

    Is there some better solution available?
