For modern engineers maintaining legacy S3C2410X products, the provided analysis and code skeleton serve as a roadmap to either revive the original -vis functionality or safely migrate it to a newer kernel using the IIO framework. Always consult the S3C2410X user manual (revision 1.2) and the specific Delta peripheral's datasheet—timing mismatches between the two are the primary source of "ghost touches" or video corruption. #include &lt;linux/module
