Subject: [PATCH 03/10] mfd: syscon: Add platform data with a regmap config name
Date: Mon, 28 Apr 2014 18:57:50 +0100 [thread overview]
Message-ID: <1398707877-22596-4-git-send-email-pawel.moll@arm.com> (raw)
In-Reply-To: <1398707877-22596-1-git-send-email-pawel.moll@arm.com>
Define syscon platform data structure that can be used
to define a regmap config name. This is particularly useful
in the regmap debugfs when there is more than one syscon
device registered, to distinguish the register blocks.
