Does anyone know? Digging in history, commit claims this was for S3C6410 NCP board (with Samsung S3C6410 SoC), which had a board-file: arch/arm/mach-s3c64xx/mach-ncp.c But the touchscreen was never added to the board file, thus mainline kernel never had it fully working. The NCP board file was finally removed in v6.3 in commit: 743c8fbb90ca4c02bdf4087fa9f1885ddd85041b I say drop the driver. Best regards, Krzysztof
