Subject: [PATCH v2 20/21] pinctrl: mvebu: dove: use global register regmap
Date: Tue, 28 Jan 2014 01:39:32 +0100 [thread overview]
Message-ID: <1390869573-27624-21-git-send-email-sebastian.hesselbarth@gmail.com> (raw)
In-Reply-To: <1390869573-27624-1-git-send-email-sebastian.hesselbarth@gmail.com>
Now that we have a regmap for global registers, get rid of the last
remaining hardcoded physical addresses. While at it, also remove
DOVE_ prefix from those macros.
