From 5d47dbc85228de3ce82dea11af3c169e66cbf520 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Wed, 24 Apr 2013 13:32:51 +0300 Subject: [PATCH] OMAPDSS: public omapdss_register_output() In order to allow multiple display block in a video pipeline, we need to give the drivers way to register themselves. For now we have the omapdss_register_display() which is used to register panels, and dss_register_output() which is used to register DSS encoders. This patch makes dss_register_output() public (with the name of omapdss_register_output), which can be used to register also external encoders. The distinction between register_output and register_display is that a "display" is an entity at the end of the videopipeline, and "output" is something inside the pipeline. The registration and naming will be made saner in the future, but the current names and functions are kept to minimize changes during the dss device model transition.
