[Buildroot] [PATCH] Xorg and Tslib

[Sergio Prado]

Hello guys!

First of all, congratulations for the great work you have been doing
on the Buildroot project!

That's my first message on the group. I have been using Buildroot
professionally for some time now.

Nowadays I have a training company here in Brazil, and guess what I am
using to teach embedded Linux? Buildroot, of course! :)

OK, so now that I have introduced myself, I would like to talk about
about a problem I was having here with X11 and touch screen devices.

I have generated a rootfs with X11 and Matchbox support. Everything
but the touchscreen works fine. I could use the ts_calibrate and
ts_test tools to test the TS device. But when I started X11/Matchbox,
the cursor was not calibrated.

Then I discovered that for X11 to talk directly to TS devices, it
needs the xf86-input-tslib driver. And we don't have it on Buildroot
(as far as I understood, it was developed by the Ubuntu team, not the
xorg team).

I integrated this package to the Buildoot build system, compiled and
tested. Everything is working now.

Here is the patch to include the xf86-input-tslib driver:
