From a5bbad258a9ec41df4a158c828b9ef0af7955854 Mon Sep 17 00:00:00 2001 From: "Claudiu.Beznea@microchip.com" Date: Tue, 21 Jan 2020 10:03:32 +0000 Subject: power: reset: at91-reset: introduce struct at91_reset_data Introduce struct at91_reset_data to be able to provide per SoC data. At the moment this being only notifier callback.
