Adding the device model into the device name is useful when
applications need to set different parameters according to the
touchscreen being used, e.g. X11 calibration points.

Which ilitek devices do you have available exactly ?

There is a firmware interface which does report the device type, but I 
don't know whether it works on all the ilitek touchscreen devices. If it 
does, then it could be used here to pull the type from the firmware and 
then use this instead

snprintf(model_name, ILI_NAME_LEN, "Ilitek ILI%04x Touchscreen", type);

Try this command against the touch controller, it sends it command 0x61 
and reads two bytes of the reply:
i2ctransfer -f -y 1 w1@0x41 0x61 r2
0x10 0x25 # <---- on ILI2510 it reports 0x25 0x10 in reverse

Thanks for the comments and suggestions. I'll make the changes and send V2.

Can you tell which ILI2xxx touch controller you have exactly ?

Can you share the output of the 'i2ctransfer' (from i2c-tools) command 
above ?

Now I have only the ILI2511. Will also have to support ILI2510 and ILI2118.

# i2ctransfer -f -y 3 w1@0x41 0x61 r2
0x11 0x25

Nice, so this works at least with the 251x series. Let's see how the 
2118 behaves, I bet you will get 0x18 0x21 there too.
