So it will be a problem when syncing kernel dts. Can you move this to r5 dts? Thanks and regards, Lokesh

Main domain ESM support is needed to configure main domain watchdogs to generate ESM pin events by default. On J7 processor board these propagate to the PMIC to generate a reset when watchdog expires.
