Subject: [PATCH 1/5] pinctrl: berlin: regmap as an extra argument of berlin_pinctrl_probe()
Date: Sat, 19 Sep 2015 18:02:32 +0800 [thread overview]
Message-ID: <1442656956-5740-2-git-send-email-jszhang@marvell.com> (raw)
In-Reply-To: <1442656956-5740-1-git-send-email-jszhang@marvell.com>
Let berlin_pinctrl_probe() accepts an extra argument: regmap, this is to
prepare for the next berlin4ct support, where we won't use simple-mfd
any more.
