- *
- *  Compaq touchscreen protocol driver. The protocol emulated by this driver
- *  is obsolete; for new programs use the tslib library which can read directly
- *  from evdev and perform dejittering, variance filtering and calibration -
- *  all in user space, not at kernel level. The meaning of this driver is
- *  to allow usage of newer input drivers with old applications that use the
- *  old /dev/h3600_ts and /dev/h3600_tsraw devices.
- *
- *  09-Apr-2004: Andrew Zabolotny <zap@homelink.ru>
- *      Fixed to actually work, not just output random numbers.
- *      Added support for both h3600_ts and h3600_tsraw protocol
- *      emulation.

-/* This driver emulates both protocols of the old h3600_ts and h3600_tsraw
- * devices. The first one must output X/Y data in 'cooked' format, e.g.
- * filtered, dejittered and calibrated. Second device just outputs raw
- * data received from the hardware.
- *
- * This driver doesn't support filtering and dejittering; it supports only
- * calibration. Filtering and dejittering must be done in the low-level
- * driver, if needed, because it may gain additional benefits from knowing
- * the low-level details, the nature of noise and so on.
- *
- * The driver precomputes a calibration matrix given the initial xres and
- * yres values (quite innacurate for most touchscreens) that will result
- * in a more or less expected range of output values. The driver supports
- * the TS_SET_CAL ioctl, which will replace the calibration matrix with a
- * new one, supposedly generated from the values taken from the raw device.
