Subject: [PATCH/RFC 10/7] ARM: OMAP2+: Remove DSI pin muxing
Date: Wed, 14 Dec 2016 03:58:02 +0200	[thread overview]
Message-ID: <1481680684-11585-3-git-send-email-laurent.pinchart@ideasonboard.com> (raw)
In-Reply-To: <1481680684-11585-1-git-send-email-laurent.pinchart@ideasonboard.com>

The DSI pin muxing platform callbacks are unused, remove them.
