Input: elantech - add special check for fw_version 0x470f01 touchpad

2015-08-07T21:54:15Z

It is no need to check the packet[0] for sanity check when doing elantech_packet_check_v4() function for fw_version = 0x470f01 touchpad. Signed-off by: Duson Lin Reviewed-by: Ulrik De Bie Signed-off-by: Dmitry Torokhov

Input: elantech - force resolution of 31 u/mm

2015-07-16T17:47:31Z

All Elantech touchpads pre-v4 with dynamic resolution queries have a fixed resolution of 800dpi -> 31.49 units/mm. Set this statically, so userspace does not have to guess. Signed-off-by: Peter Hutterer Reviewed-by: Hans de Goede Reviewed-by: David Herrmann Signed-off-by: Dmitry Torokhov

Input: elantech - add new icbody type

This adds new icbody type to the list recognized by Elantech PS/2 driver. Cc: stable@vger.kernel.org Signed-off-by: Sam Hung Signed-off-by: Dmitry Torokhov

Input: elantech - fix detection of touchpads where the revision matches a known rate

2015-06-02T17:43:07Z

Make the check to skip the rate check more lax, so that it applies to all hw_version 4 models. This fixes the touchpad not being detected properly on Asus PU551LA laptops.

Input: elantech - fix semi-mt protocol for v3 HW

2015-05-13T17:31:22Z

When the v3 hardware sees more than one finger, it uses the semi-mt protocol to report the touches. However, it currently works when num_fingers is 0, 1 or 2, but when it is 3 and above, it sends only 1 finger as if num_fingers was 1. This confuses userspace which knows how to deal with extra fingers when all the slots are used, but not when some are missing.

Input: elantech - fix absolute mode setting on some ASUS laptops

2015-04-06T22:39:07Z

On ASUS TP500LN and X750JN, the touchpad absolute mode is reset each time set_rate is done. In order to fix this, we will verify the firmware version, and if it matches the one in those laptops, the set_rate function is overloaded with a function elantech_set_rate_restore_reg_07 that performs the set_rate with the original function, followed by a restore of reg_07 (the register that sets the absolute mode on elantech v4 hardware). Also the ASUS TP500LN and X750JN firmware version, capabilities, and button constellation is added to elantech.c Cc: stable@vger.kernel.org Reported-and-tested-by: George Moutsopoulos Signed-off-by: Ulrik De Bie Signed-off-by: Dmitry Torokhov

Input: elantech - add more Fujtisu notebooks to force crc_enabled

Input: elantech - support new ICs types for version 4

This change allows the driver to recognize newer Elantech touchpads. Cc: stable@vger.kernel.org Signed-off-by: Yi ju Hong Signed-off-by: Dmitry Torokhov

Input: elantech - trust firmware about trackpoint presence

2014-11-25T08:42:13Z

Only try to parse data as coming from trackpoint if firmware told us that trackpoint is present. Fixes commit caeb0d37fa3e387eb0dd22e5d497523c002033d1 Reported-and-tested-by: Marcus Overhagen Reported-and-tested-by: Anders Kaseorg Signed-off-by: Dmitry Torokhov

Input: elantech - provide a sysfs knob for crc_enabled

2014-11-14T01:50:23Z

The detection of crc_enabled is known to fail for Fujitsu H730. A DMI blacklist is added for that, but it can be expected that other laptops will pop up with this. Here a sysfs knob is provided to alter the behaviour of crc_enabled. Writing 0 or 1 to it sets the variable to 0 or 1. Reading it will show the crc_enabled variable (0 or 1).
