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?

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
