Subject: [PATCH 0/3] input: ft5x06: Fix userspace reported maximum value

Hi,

The current ft5x06 reports to the user-space that its maximum
coordinates are, on both X and Y, way higher than what could be
actually usable on the screen (in my case, 5759x1151 instead of
480x800).

This causes trouble on some userspace stacks that then try to re-scale
these coordinates back to the framebuffer resolution, like QT does.

Use the of_touchscreen code to find the real touchscreen limits in the
DT case, and report that to the userspace.

Thanks,
Maxime
