A touchscreen driver has been posted upstreams

[Sveinung Kvilhaugsvik]

A touch screen driver for S3C24XX has been posted to
linux-arm-kernel[1]. What does this mean for the one in andy-tracking?
Will there be an attempt to upstream it? Will it be dropped in favor
of the one posted to linux-arm-kernel?

Hello Sveinung.

I just replied there. I will not try sending our version upstream. Too
much noise :-) I didn't notice the other version of the driver before
because it was not sent there by Ben.

http://www.spinics.net/lists/arm-kernel/msg72531.html

I've read the idea is to see which version is more suitable for
upstream and include it.

Regards.

An update on the situation for us that are interested in upstreams
Freerunner support but don't subscribe to all the upstream lists: Ben
Dooks posted his touchscreen driver for S3C24XX (a different one) at

The driver was just accepted but it's not in the Linus tree yet.

There is some information we could use but I guess we will have to try
something with tslib before asking them to send all the points to
users-pace instead of averaging them as it is done now.

+ if (ts.count == (1 << ts.shift)) {
+ ts.xp >>= ts.shift;
+ ts.yp >>= ts.shift;

Long discussion here:

Something nice about this new version of the driver (something other
than being a clean driver) is that the original driver authors are
properly credited.

Thanks for this link, it's (somewhat) enlightening (but also
frightening) to see that opinions haven't changed in the five years
since I stopped reading lakml. Both the userland and the kernel
touchscreen filtering crowd are pretty much refusing to even consider
the other parties arguments. *sigh*
