From: Archit Taneja Date: Wed, 26 Sep 2012 11:12:39 +0000 (+0530) Subject: OMAPDSS: APPLY: Add manager set/unset output ops for omap_overlay_manager X-Git-Tag: firefly_0821_release~3680^2~1437^2^2~85^2~17 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=97f01b3a2ed6d46132bf4e2d237c27846e7b260a;p=firefly-linux-kernel-4.4.55.git OMAPDSS: APPLY: Add manager set/unset output ops for omap_overlay_manager Add set_output/unset_output ops for overlay managers, these form links between managers and outputs. Create a function in dss features which tell all the output instances that connect to a manager, use it when a manager tries to set an output. Add a constraint of not unsetting an output when the manager is enabled. Keep the omap_dss_device pointer and set/unset_device ops in overlay_manager for now to not break things. Keep the dss feature function get_supported_displays as it's used in some places. These will be removed later.
