Hi Pratyush,
Great thanks for your help on some update for watchdog framework.
For " Fix parent of watchdog_devices", I will update my patchset. For the upstreaming patchset"Sysfs status read support", will make a patch. But upstream it when your patchset is merged.

In general the idea here would be to use a crashdump kernel, which, when loaded, would reset the watchdog before it fires. This kernel would then write a core dump to a specified location.
And this is what we do in fedora or RHEL. There had been some work ongoing in fedora [1][2] which will help to reset any active watchdog in kdump kernel(if the watchdog driver has been registered to watchdog_class). It will eventually help a watchdog on ARM64 platform as well.
