Untouched TouchScreen for Raspberry PI 2 pt1

And finally I have got a time to setup TouchScreen for my Rpi2. And I shat say that it wasn't easy.

What I have had:
- Rpi2
- 3.5" TFT LCD Touch Screen Module 320*480 RGB Display Board with logo of WaveShare SpotPear

I have found one article with tutorial It uses common custom driver for Touch LCDs But author of this article has different module with different controller.

But my module has XPT2046 controller and it requires slightly different setup command. Lets see those differences

$ sudo nano /etc/modules

$ sudo nano /boot/cmdline.txt

$ sudo nano /boot/config.txt

we use config.txt and device tree overlays because in actually firmware of Rpi2 no longer uses ads7846_device.

so with those changes LCD screen works fine. But touch interface still doesn’t work I will do more investigations later, when I will get more free time. but if you have had same problem but now fixed it, please put comment here with right solution.
