Mainly the I2C pins are connected to any i2c port on the CPU and is used to communicate with the touchscreen. In the other way a resistive touchscreen has 4 wires. Details can be found in the user manuals for Allwinner chips, in the section TP touch panel.
Testing was done on an A20 platform and gave exceptionally good results.
Usually any touchscreen has a startup procedure during which resets are sent to the touchscreen by the cpu to indicate this procedure.
Also in some cases the I2C address is set by this rest procedure for instance, GT The interrupt Pin can be part of the startup procedure for handshakes or indications. In some cases the interrupt pin is also used as input to read additional data from the cpu during reset.
This configuration is sent during or right after the reset procedure of the touchscreen and is usually written to the controller memory in some cases selectable persistent in eeprom. The preferred mode a capacitive touchscreen should work in is always interrupt mode. In Polling mode the cpu periodically requests the touchscreen data from the touchscreen. This means that there will be a lot of communication on the i2c port since this has to happen once every few ms.
Now you need to find our your i2c address of your touchscreen. Note that on some touchscreens ft5x it is required to define another port called the IO port on the same port as the interrupt port:. This setting will define the same port with mux setting 0 as output to allow the driver to switch to IO mode. There can be problems with produced configuration so it's good to test and see what's actually happening. Try to move your finger over the screen and see if there's some sings of miscalibration.
Produced config actually scales values from touchscreen controller to map to the screen so it may happen that one axis works ok and another doesn't. Detailed list of options can be found in the evdev manual page. Elan Microelectronics Corporation.
