From 55cd63acf6855cd45a183fdfca6d22450b8d1d47 Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Thu, 9 Aug 2012 15:41:13 +0530 Subject: [PATCH] OMAPDSS: DSI: Update manager timings on a manual update During a command mode update using DISPC video port, we may need to swap the connected overlay manager's width and height when 90 or 270 degree rotation is done via the panel by changing it's address mode. Call dss_mgr_set_timings() in update_screen_dispc() before starting the manager update. The new manager size is updated in the 'timings' field of DSI driver's private data via omapdss_dsi_set_size(). A panel driver is expected to call this when performing rotation.
