Here is the series to enable the RWDT on V3U. I took the DTS patches from the BSP, the rest was developed on mainline tree. Note that currently, the bootloader does not unmask the RWDT reset for us. This is why patch #5 is needed if you want a reboot. We need to see if this is going to be added to the bootloader later. Also, while the normal watchdog trigger works flawlessly, the 'reboot' command will triger a OOPS. This is a known issue also present on other Gen3 SoCs and will be addressed seperately soon. Other than that, patch #1 should go in via watchdog, the rest via Geert's various trees :) Looking forward to comments. Happy hacking and have a nice weekend!
