[tslib] Setting ts_calibrate results EVIOCSABS

[Baruch Siach]

Hi tslib list,

Is it possible to set the ts_calibrate results into the kernel input layer 
using the EVIOCSABS ioctl()? That would make the calibration instantly 
available to all touchscreen input device users, independent from the tslib 
library.

The problem I am facing is that I'm on X11, stuck with an old kernel (pre 
of_touchscreen.c), and a Debian installation that does not package 
xf86-input-tslib. The xf86-input-evdev Calibration option doesn't work at all 
for some reason.

Looking around I could not find any EVIOCSABS user. The EVIOCSABS ioctl() as 
been in the kernel since pre-git times.

Am I missing something obvious here?

FWIW, the touchscreen driver is edt-ft5x06.c, that works nicely except from 
the calibration. Both X and Y are reported x2 at the X11 level.

Thanks,
baruch
