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. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
