I am not sure we are talking about same thing... I do not really care whether it is named "hid i2c" or "i2chid". What I meant if the device really speaks HID protocol, except that the transport is not USB or bluetooth but I2C, then instead of writing a custom driver for this particular part we need to add a new HID transport into drivers/hid/i2c-hid that is similar to drivers/hid/usbhid/ and reuse the rest of HID framework along with hid- multitouch.c which handles HID-compliant multitouch devices. I am CCing Jiri (HID maintainer) for additional input.
