Input: elantech - mark protocols v2 and v3 as semi-mt

2016-01-12T01:45:32Z

When using a protocol v2 or v3 hardware, elantech uses the function elantech_report_semi_mt_data() to report data. This devices are rather creepy because if num_finger is 3, (x2,y2) is (0,0). Yes, only one valid touch is reported. Anyway, userspace (libinput) is now confused by these (0,0) touches, and detect them as palm, and rejects them. Commit 3c0213d17a09 ("Input: elantech - fix semi-mt protocol for v3 HW") was sufficient enough for xf86-input-synaptics and libinput before it has palm rejection. Now we need to actually tell libinput that this device is a semi-mt one and it should not rely on the actual values of the 2 touches.

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 - 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
