Subject: [PATCH 1/3] misc: m48t59: replace qemu_system_reset_request() call with watchdog_perform_action()
Date: Fri, 16 Feb 2024 19:21:37 +0530 [thread overview]
Message-ID: <20240216135137.8668-4-atp.exp@gmail.com> (raw)
In-Reply-To: <20240216135137.8668-3-atp.exp@gmail.com>
A few watchdog devices use qemu_system_reset_request(). This is not ideal since
behaviour of watchdog-expiry can't be changed by QMP using `watchdog_action`.
As stated in BiteSizedTasks wiki page, instead of using qemu_system_reset_request()
to reset when a watchdog timer expires, let watchdog_perform_action() decide
what to do.
