Hi Tom,
https://lore.kernel.org/linux-arm-kernel/5187c590-ee9a-4c46-b326-655f4c371...@linaro.org/T/#me178708007a6b3b9695ae0ff84475fa4f49f283c
I have posted the ESM patches to the linux kernel device tree mailing
list. These are neeeded in R5 SPL to enable watchdog support.

Patch adds the ESM instances for j721s2. It has 3 instances.
One in the main domain and two in the mcu-wakeup domian.
