  Input: appletouch - another fix for idle reset logic
  HWMON: hdaps - switch to using input-polldev
  Input: add support for SEGA Dreamcast keyboard
  Input: omap-keyboard - don't pretend we support changing keymap
  Input: lifebook - fix X and Y axis range
  Input: usbtouchscreen - add support for GeneralTouch devices
  Input: fix open count handling in input interfaces
  Input: keyboard - add CapsShift lock
  Input: adbhid - produce all CapsLock key events
  Input: ALPS - add signature for ThinkPad R61
  Input: jornada720_kbd - send MSC_SCAN events
  Input: add support for the HP Jornada 7xx (710/720/728) touchscreen
  Input: add support for HP Jornada 7xx onboard keyboard
  Input: add support for HP Jornada onboard keyboard (HP6XX)
  Input: ucb1400_ts - use schedule_timeout_uninterruptible
  Input: xpad - fix dependancy on LEDS class
  Input: auto-select INPUT for MAC_EMUMOUSEBTN option
  ...

Resolved conflicts manually in drivers/hwmon/applesmc.c: converting from
a class device to a device and converting to use input-polldev created a
few apparently trivial clashes..

* 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* is obsolete; for new programs use the tslib library which can read directly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.
