Subject: [RFC PATCH 17/29] OMAPDSS: DISPC: Make dispc_ovl_setup call dispc_plane_setup
Date: Tue, 27 Dec 2011 18:07:00 +0530	[thread overview]
Message-ID: <1324989432-3625-18-git-send-email-archit@ti.com> (raw)
In-Reply-To: <1324989432-3625-1-git-send-email-archit@ti.com>

Add a new static function called dispc_plane_setup(). This function is used by
dispc_ovl_setup() to configure the overlay registers.

This split is done so that dispc_wb_setup() can reuse the common overlay related
registers configured in dispc_plane_setup().
