Subject: [PATCH 08/15] power: reset: at91-reset: introduce struct at91_reset_data
Date: Tue, 21 Jan 2020 10:03:32 +0000 [thread overview]
Message-ID: <1579601001-5711-9-git-send-email-claudiu.beznea@microchip.com> (raw)
In-Reply-To: <1579601001-5711-1-git-send-email-claudiu.beznea@microchip.com>
Introduce struct at91_reset_data to be able to provide per SoC
data. At the moment this being only notifier callback.
