Subject: [PATCH 16/21] OMAPDSS: DISPC: Add function to set channel in for writeback
Date: Thu, 13 Sep 2012 12:27:00 +0000 [thread overview]
Message-ID: <1347538505-25359-17-git-send-email-archit@ti.com> (raw)
In-Reply-To: <1347538505-25359-1-git-send-email-archit@ti.com>
Writeback can take input from either one of the overlays, or one of the overlay
managers. Add an enum which represents the channel_in for writeback, and maps
to the register field programming.
Add a function to configure channel in for writeback. This will be used later in
APPLY.
