From 54128701ecccbeb6f740030e0cc5f8e5701fe8ee Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Thu, 8 Sep 2011 11:29:17 +0530 Subject: OMAPDSS: DISPC: zorder support for DSS overlays Add zorder support on OMAP4, this feature allows deciding the visibility order of the overlays based on the zorder value provided as an overlay info parameter or a sysfs attribute of the overlay object. Use the overlay cap OMAP_DSS_OVL_CAP_ZORDER to determine whether zorder is supported for the overlay or not. Use dss feature FEAT_ALPHA_FREE_ZORDER if the caps are not available. Ensure that all overlays that are enabled and connected to the same manager have different zorders. Swapping zorders of 2 enabled overlays currently requires disabling one of the overlays.
