From beb8384d4a67179e8c207f00e9035ab121ed5940 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Thu, 5 Jun 2014 11:35:10 +0300 Subject: [PATCH] OMAPDSS: DISPC: reject interlace for lcd out OMAP2/3 does not support interlace for LCD out. OMAP4+ does, but is not supported by the driver at the moment. The driver still accepts interlaced mode for LCD out, causing broken display output. This patch makes dispc reject interlace for LCD out.
