Input: alps - fix touchpad buttons getting stuck when used with trackpoint

2015-05-06T20:03:49Z

commit 6bcca19f5dcedc3a006ca0bcc3699a437cadee74 upstream. When the left touchpad button gets pressed, and then the trackpoint is moved, and then the button is released, the following happens: 1) touchpad packet is received, touchpad evdev node reports BTN_LEFT 1 2) pointing stick packet is received, the hw will report a BTN_LEFT 1 in this packet because when the trackstick is active it communicates the combined touchpad + pointing stick buttons in the trackstick packet, since alps_report_bare_ps2_packet passes NULL (*) for the dev2 parameter to alps_report_buttons the combining is not detected and the pointing stick evdev node will also report BTN_LEFT 1 3) on release of the button a pointing stick packet with BTN_LEFT 0 is received and the pointing stick evdev node will report BTN_LEFT 0 Note how because of the passing as NULL for dev2 the touchpad evdev node will never send BTN_LEFT 0 in this scenario leading to a stuck mouse button. This is a regression in 4.0 introduced by commit 04aae283ba6a8 ("Input: ALPS - do not mix trackstick and external PS/2 mouse data") This commit fixes this by passing in the touchpad evdev as dev2 parameter when calling alps_report_buttons for the pointingstick on alps v2 devices, so that alps_report_buttons correctly detect that we're already reporting the button as pressed via the touchpad evdev node, and will also send the release event there.

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

2015-05-06T20:03:49Z

commit bd884149aca61de269fd9bad83fe2a4232ffab21 upstream. 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 Reported-and-tested-by: George Moutsopoulos Signed-off-by: Ulrik De Bie Signed-off-by: Dmitry Torokhov Signed-off-by: Greg Kroah-Hartman

Input: alps - report V2 Dualpoint Stick events via the right evdev node

2015-04-05T18:48:35Z

On V2 devices the DualPoint Stick reports bare packets, these should be reported via the "AlpsPS/2 ALPS DualPoint Stick" dev2 evdev node, which also has the INPUT_PROP_POINTING_STICK propbit set. Note that since there is no way to distinguish these packets from an external PS/2 mouse (insofar as these laptops have an external PS/2 port) this means that we will be reporting PS/2 mouse events via this evdev node too, as we've been doing in kernel 3.19 and older. This has been tested on a Dell Latitude D620 and a Dell Latitude E6400, which both have a V2 touchpad + a DualPoint Stick which reports bare packets.

Input: alps - report interleaved bare PS/2 packets via dev3

2015-04-05T18:48:34Z

Bare packets should be reported via the same evdev device independent on whether they are detected on the beginning of a packet or in the middle of a packet. This has been tested on a Dell Latitude E6400, where the DualPoint Stick reports bare packets, which get reported via dev3 when the touchpad is idle, and via dev2 when the touchpad and stick are used simultaneously. This commit fixes this inconsistency by always reporting bare packets via dev3. Note that since the come from a DualPoint Stick they really should be reported via dev2, this gets fixed in a later commit.

Lenovo X250 has a PnpID of LEN0046, but it does not have the top software button requirement. For the record, Lenovo T450s and W541 have a PnpID of LEN200f and LEN004a, so they are not on the top software button list.
