Wait... Checking the Makefile in the drivers/watchdog directory: ifneq (,$(filter $(SOC), mx31 mx35 mx5 mx6 vf610)) obj-y += imx_watchdog.o endif That is: watchdog is supported for other i.MX families. It is not surprising if it is not working, I am surprised that hw_watchdog_init is called, because imx_watchdog should not be compiled. I have not checked inside MX23 manual, but if it is as in MX28 you have to enable the watchdog inside the RTC. It works in a different way as in other imx, and the current driver is not suitable for MX23. You have to add support for it.
