I have not looked how the watchdog subsystem handles multiple watchdogs, but.. Can't we have the omap watchdog and twl watchdog return -ENOTSUPP for WDIOC_GETBOOTSTATUS and have the watchdog core fail over to the third wathcdog omap_prcm_wdt_ioctl() that only implements WDIOC_GETBOOTSTATUS? Or something like that.
