ARM: dts: logicpd-torpedo-baseboard: Fix missing video
A previous commit removed the panel-dpi driver, which made the Torpedo video stop working because it relied on the dpi driver for setting video timings. Now that the simple-panel driver is available in omap2plus, this patch migrates the Torpedo dev kits to use a similar panel and remove the manual timing requirements. Fixes: 8bf4b1621178 ("drm/omap: Remove panel-dpi driver") Signed-off-by: Adam Ford <aford173@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
