Subject: [PATCH 09/15] power: reset: at91-reset: introduce args member in at91_reset_data
Date: Tue, 21 Jan 2020 10:03:33 +0000 [thread overview]
Message-ID: <1579601001-5711-10-git-send-email-claudiu.beznea@microchip.com> (raw)
In-Reply-To: <1579601001-5711-1-git-send-email-claudiu.beznea@microchip.com>
Introduce args member in struct at91_reset_data. It stores the value
that needs to be written in mode register so that the reboot actions
to happen. With these changes samx7_restart() could be removed.
