twl4030_wdt driver and omap_wdt driver are registering as misc_device name as "watchdog" and the same minor number WATCHDOG_MINOR( value = 130). There is a conflict since the name and minor were the same for both the misc_device registered by omap_wdt.c as well as twl4030_wdt.c The omap_wdt.c probe is getting called first. Hence it succeeds. twl4030_wdt.c always failed on the minor number comparison check. Now requesting for MISC_DYNAMIC_MINOR as the minor number for twl4030_watchdog and renamed the device name as "twl4030_watchdog". Tested for basic boot up on OMAP4 Blaze and OMAP3630 SDP. OMAP3630 SDP twl4030_wdt registration succeeds.2430SDP boot tested, watchdog registration without errors.
