Subject: [PATCH 2/3] ARM: at91: pm: group constants and addresses loading
Date: Tue, 28 Sep 2021 11:42:56 +0300 [thread overview]
Message-ID: <20210928084257.2188017-3-claudiu.beznea@microchip.com> (raw)
In-Reply-To: <20210928084257.2188017-1-claudiu.beznea@microchip.com>
Group constants and addresses loading. This commit prepares the field for
the next one. Added fixes tag on this commit as the next one will fail
to apply if backported alone to older kernels.
Fixes: f0bbf17958e8 ("ARM: at91: pm: add self-refresh support for sama7g5")
Signed-off-by: Claudiu Beznea <claudiu.beznea@microchip.com>
