From 408d9dbbc4eebd8c4f2cd5d487f1b9c3c12c2c59 Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Mon, 7 May 2012 16:51:36 +0530 Subject: [PATCH] OMAPDSS: DISPC: Remove Fake VSYNC support Fake VSYNC support is a hack and has some bugs in it. It isn't used by any user of DSS. Remove Fake VSYNC support. For DSI command mode and RFBI panels, a user of DSS should wait for the completion of a frame by using the panel driver's sync op.
