You will need board code to register the OMAP3 ISP platform device that will then be picked by the OMAP3 ISP driver. Example of such board code can be found at http://git.linuxtv.org/pinchartl/media.git/commit/37f505296ccd3fb055e03b2ab15ccf6ad4befb8d -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
