The effect was strange: only the Blue channel of the RGB panel was driven while Red and Green stayed black. So a coloured picture turned into blue/black. The GTA04 with DM3730 didn't show the effect. It turned out that VDDS_DSI was not properly initialized on OMAP3530, because the .family string is just "OMAP3" for these processors and not "OMAP3xxx". Therefore we match the .machine attribute.
