Unable to get i.MX7 Watchdog 2, 3, 4 to work

Hi, We are using i.MX7S. Only A7 core is used. We tried to get watchdog2-4 to work without success. We can get watchdog1 to work without any issue. We tried the same code on NXP Sabre board with the same unsuccessful result. We turned on IPG_CLK_ROOT, WDOG_CLK_ROOT and all the clock gates (CCGR156-159). We are not sure if there are special registers that are needed to be set, particularly in area like clock input to the watchdog module. If you have experience with WDOG2-4 especially WDOG4 please help. A little code would be very helpful. Thanks.
