Subject: [PATCH 03/14] OMAPDSS: DSI: simplify dsi configuration
Date: Fri, 08 Mar 2013 11:52:38 +0000 [thread overview]
Message-ID: <1362743569-10289-4-git-send-email-tomi.valkeinen@ti.com> (raw)
In-Reply-To: <1362743569-10289-1-git-send-email-tomi.valkeinen@ti.com>
We have a bunch of dsi functions that are used to do the basic
configuration for DSI. To simplify things, and to make sure we have all
the necessary information, create a single dsi config function, which
does the basic configuration.
