      Input: add MT_TOOL_PALM · a736775d
      Charlie Mooney authored
      Currently there are only two "tools" that can be specified by a multi-touch
      driver: MT_TOOL_FINGER and MT_TOOL_PEN. In working with Elan (The touch
      vendor) and discussing their next-gen devices it seems that it will be
      useful to have more tools so that their devices can give the upper layers
      of the stack hints as to what is touching the sensor.
      
      In particular they have new experimental firmware that can better
      differentiate between palms vs fingertips and would like to plumb a patch
      so that we can use their hints in higher-level gesture soft- ware.  The
      firmware on the device can reasonably do a better job of palm detection
      because it has access to all of the raw sensor readings as opposed to just
      the width/pressure/etc that are exposed by the driver.  As such, the
      firmware can characterize what a palm looks like in much finer-grained
      detail and this change would allow such a device to share its findings with
      the kernel.

      Slot 0 and 1 gets inverted in the second report above, which
      introduces a cursor jump. The problem is that this cursor jump is
      often enough to leave the current widget, and X sends the
      scrolling events to whoever is now under the cursor.

      Input: sun4i-ts - add thermal driver dependency · 4a6155a4
      Arnd Bergmann authored
      The sun4i-ts driver has had a dependency on the thermal code
      with the addition of the thermal zone sensor support, but this
      is not currently enforced in Kconfig, so with TOUCHSCREEN_SUN4I=y,
      THERMAL=m and THERMAL_OF=y we get
      
      drivers/built-in.o: In function `sun4i_ts_remove':
      :(.text+0x2376f4): undefined reference to `thermal_zone_of_sensor_unregister'
      drivers/built-in.o: In function `sun4i_ts_probe':
      :(.text+0x237a94): undefined reference to `thermal_zone_of_sensor_register'
      :(.text+0x237c00): undefined reference to `thermal_zone_of_sensor_unregister'
      
      We need the dependency on THERMAL in order to ensure that this
      driver becomes a loadable module if the thermal support itself
      is modular, while the dependency on THERMAL_OF is a runtime
      dependency and the driver will still build if it is missing.
      It is entirely possible to build sun4i-ts without THERMAL_OF
      just to use the hwmon sensors and/or touchscreen.

      Input: cyapa - remove superfluous type check in cyapa_gen5_read_idac_data() · 2523caab
      Geert Uytterhoeven authored
      drivers/input/mouse/cyapa_gen5.c: In function ‘cyapa_gen5_read_idac_data’:
      drivers/input/mouse/cyapa_gen5.c:1876: warning: ‘max_element_cnt’ may be used uninitialized in this function
      drivers/input/mouse/cyapa_gen5.c:1873: warning: ‘offset’ may be used uninitialized in this function
      
      If *data_size is non-zero, and idac_data_type contains an unknown type,
      max_element_cnt and offset will be uninitialized, and the loop will
      process non-existing data.
      
      However, this cannot happen (for now), as there's a test for unknown
      types at the top of cyapa_gen5_read_idac_data().
      
      As no "if ... else if ..." is used in other places, remove the
      superfluous "if" to silence the compiler warning.
