Property "fsl,wdt-continue-in-low-power" allows the watchdog to continue running in low power modes (STOP and DOZE). By default, the watchdog is suspended in these modes. This property provides the option to keep the watchdog active during low power states when needed. Signed-off-by: Nandor Han <redacted>
Do not attach (thread) your patchsets to some other threads (unrelated or older versions). This buries them deep in the mailbox and might interfere with applying entire sets. See also: https://elixir.bootlin.com/linux/v6.16-rc2/source/Documentation/process/submitting-patches.rst#L830

Not much improved. My questions how this petting is suppose to work remain unanswered. Again, system load is really not relevant whether watchdog works or not in low power mode. Best regards, Krzysztof
