According to the i.MX 6UltraLite Applications Processor Reference Manual, Rev. 1, 04/2016, Table 2-3. AIPS-2 memory map, there is a WDOG3. The memory is allocated at start address 0x021E4000.
However, the device tree file imx6ull.dtsi for the i.MX6ULL in the linux-imx.git repository does not have a wdog3 node as a child of aips2: linux-imx.git - i.MX Linux Kernel
Is there any reason why wdog3 is missing?
Is there any chance the linux-imx repository will be updated, as the last change is 10 months ago?
