Yes, there was a commit in mainline that removed platform support since all in-tree users was using Device Tree. This is a Device Tree overlay example for Raspberry Pi: https://github.com/notro/fbtft/blob/master/dts/overlays/rpi/pitft28-resistive-overlay.dts

You're welcome :-)

But the problem is not solved with the dts file. So I have to do some changes on the stmpe_device.c. Has anyone did this changes?

stmpe_device can't work with the latest kernel, because platform_data support has been removed. So unless you revert the commit somehow, you're stuck with Device Tree.
