SubjectRe: [PATCH v2 6/7] Watchdog: introduce ARM SBSA watchdog driver
From
Hi Timur,

I have said this before:

in the first timeout, just panic() maybe not enough, in [RFC]
version of my patchset, I offer some option as "preaction" to use, but
for simplifying the first version of driver, I have deleted them.
but at least, panic() is far more useful than a simple reset. at
least, it can provide the context of the crashed system to admin.

If you want to warn user space, that will make driver more
complicated, I don't think that is a good choose for a first version.
but we can find a way to improve this later
