Removal of MSC-5000/5080 touchscreen/touchkey drivers?
Subsystems (2)
Hi,
Sorry for a somewhat wide and random distribution, but I was wondering if anyone knows if drivers/input/touchscreen/mcs5000_ts.c and drivers/input/keyboard/mcs_touchkey.c are still relevant these days?
Looking at Melfas web-site it looks like these were the 1st generation of their chips, manufactured 2000-2007. The drivers were contributed by Samsung long time ago, they rely on custom platform data (no DT support) and as far as I can see we never had a user of them in mainline.
Should I simply remove them? Does anyone know?
Thanks.

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
