Correct. And only send once when the pen hit the touchscreen. like following:

        if(!wm->pen_is_down)
            input_report_key(wm->input_dev, BTN_TOUCH, 1);

        absx = data.x & 0xfff;
        absy = data.y & 0xfff;

        if(absy > wm->input_dev->absmax[ABS_Y])
            absy = wm->input_dev->absmax[ABS_Y];

        if(absx > wm->input_dev->absmax[ABS_X])
            absx = wm->input_dev->absmax[ABS_X];

        input_report_abs(wm->input_dev, ABS_X, absx);
        input_report_abs(wm->input_dev, ABS_Y, (wm->input_dev->absmax[ABS_Y] - absy) + wm->input_dev->absmin[ABS_Y]);
        input_report_abs(wm->input_dev, ABS_PRESSURE, data.p & 0xfff);
        input_sync(wm->input_dev);

you mean i shoul send a BTN_TOUCH pressure event.just like
input_event(ts->idev, EV_ABS, BTN_TOUCH, pressure);?

You need to send BTN_TOUCH event when the pen is down.
