Subject: [PATCH v1 0/6] Migrate watchdog reset to cyclic infrastructure
Date: Fri, 2 Sep 2022 14:10:43 +0200 [thread overview]
Message-ID: <20220902121049.1282136-1-sr@denx.de> (raw)
This patchset migrates the watchdog triggering (WATCHDOG_RESET calls)
to the newly introduced cyclic execution framework. For this, the
watchdog driver now registers a cyclic execution function for each
WDT device that needs to get serviced. Additionally the cyclic IF is
a bit extended to also support the CONFIG_HW_WATCHDOG users. It might
make sense to deprecate this HW_WATCHDOG usage at some point.
Please note that this migration work is based on the cyclic execution
infrastructure, which I posted in the last few weeks. So these cyclic
patches need to be applied for this migration to work.
Some further cleanup and improvements are possible after this patch.
E.g. Heinrich mentioned that the WATCHDOG_RESET call locations need to
get improved / changed in some places.
I've pushed a working branch here for anyone who wants to do some
testing with this patchset:

Here the log from octeon_ebb7304 compiled on this branch:

Any comments and suggestions are welcome.
Thanks,
