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

2016-02-10T03:56:36Z

[ Upstream commit 6544a1df11c48c8413071aac3316792e4678fbfb ] 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: i8042 - add Fujitsu Lifebook U745 to the nomux list

2016-02-10T03:56:18Z

[ Upstream commit dd0d0d4de582a6a61c032332c91f4f4cb2bab569 ] Without i8042.nomux=1 the Elantech touch pad is not working at all on a Fujitsu Lifebook U745. This patch does not seem necessary for all U745 (maybe because of different BIOS versions?). However, it was verified that the patch does not break those (see opensuse bug 883192: https://bugzilla.opensuse.org/show_bug.cgi?id=883192).

Input: serio - fix blocking of parport

2015-12-03T04:25:47Z

[ Upstream commit 1a5e251996e1b602f2ddc9261ee9de0ca1875bfa ] If parkbd_allocate_serio() fails to allocate memory we are releasing the parport but we missed unregistering the device. As a result this device with exclusive access to that parport remains registered. And no other device will be able to use that parport even though this driver has failed to load.

Input: psmouse - add small delay for IBM trackpoint pass-through mode

2015-12-03T04:25:32Z

[ Upstream commit 66bc2f51ef7deabc8b8f3baa98ae64b65e5e973a ] There are trackpoint devices that fail to respond to the PS2 command PSMOUSE_CMD_GETID if immediately queried after the parent device is deactivated. Add a small delay for the hardware to get in a sane state before sending any PS2 commands. One example of such a system is: Lenovo ThinkPad X120e, model 30515QG synaptics: Touchpad model: 1, fw: 8.0, id: 0x1e2b1, caps: 0xd001a3/0x940300/0x121c00, board id: 1811, fw id: 797391 Signed-off-by: Stefan Assmann Signed-off-by: Dmitry Torokhov Signed-off-by: Sasha Levin

Input: evdev - do not report errors form flush()

2015-10-07T14:12:48Z

[ Upstream commit eb38f3a4f6e86f8bb10a3217ebd85ecc5d763aae ] We've got bug reports showing the old systemd-logind (at least system-210) aborting unexpectedly, and this turned out to be because of an invalid error code from close() call to evdev devices. close() is supposed to return only either EINTR or EBADFD, while the device returned ENODEV. logind was overreacting to it and decided to kill itself when an unexpected error code was received. What a tragedy. The bad error code comes from flush fops, and actually evdev_flush() returns ENODEV when device is disconnected or client's access to it is revoked. But in these cases the fact that flush did not actually happen is not an error, but rather normal behavior. For non-disconnected devices result of flush is also not that interesting as there is no potential of data loss and even if it fails application has no way of handling the error. Because of that we are better off always returning success from evdev_flush(). Also returning EINTR from flush()/close() is discouraged (as it is not clear how application should handle this error), so let's stop taking evdev->mutex interruptibly.

Input: usbtouchscreen - avoid unresponsive TSC-30 touch screen

2015-08-27T17:25:45Z

[ Upstream commit 968491709e5b1aaf429428814fff3d932fa90b60 ] This patch fixes a problem in the usbtouchscreen driver for DMC TSC-30 touch screen. Due to a missing delay between the RESET and SET_RATE commands, the touch screen may become unresponsive during system startup or driver loading. According to the DMC documentation, a delay is needed after the RESET command to allow the chip to complete its internal initialization. As this delay is not guaranteed, we had a system where the touch screen occasionally did not send any touch data. There was no other indication of the problem. The patch fixes the problem by adding a 150ms delay between the RESET and SET_RATE commands.
