2016-03-17Input: byd - enable absolute modeRichard Pospesel
The Windows driver's settings dialog contains a visualization of the regions for the hardware edge scrolling capability, which uses a temporarily-enabled limited-resolution absolute mode. This patch enables this during normal operation, and combines the absolute packets with the existing relative packets to provide accurate absolute position and touch reporting. It also adds documentation for all known gesture packets and initialization commands.

2016-03-04Input: cyapa - fix for losing events during device power transitionsDudley Du
When changing the scan rate as part of runtime-resume process we may lose some of the events, because: 1) for gen3 trackpads, the driver must msleep() some time to ensure that the device is ready to accept next command; 2) for gen5 and later trackpads, the queue dumping function will simply ignore the events when waiting for the set power mode command response. The solution is to keep polling and report those valid events when the set power mode command is in progress.

2016-01-27Input: byd - add BYD PS/2 touchpad driverChris Diamand
Driver for the BYD BTP10463 touchpad, found in PC Specialist `Lafite' laptops. This patch sends the magic command sequence which causes the touchpad to stream intellimouse-style packets. Gestures are detected inside the touchpad, and exposed as special values in the Z component of each packet - absolute coordinates are not supported, even in the Windows driver. At present, this supports two-finger vertical and horizontal scrolling, and provides the framework to expose the other gestures it can recognize.

2016-01-11Input: elantech - mark protocols v2 and v3 as semi-mtBenjamin Tissoires
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.

2015-12-17Input: psmouse - limit protocols that we try on passthrough portsDmitry Torokhov
PS/2 protocol is slow, and using it with pass-through port (where we encapsulate PS/2 into PS/2) is slower yet so it takes quite a bit of time to do full protocol discovery for device attached to a pass-through port. However, so far we have not see anything but trackpoints or basic PS/2 mice on pass-through ports, so let's limit protocols that we probe there to Trackpoint, IntelliMouse Explorer, IntelliMouse, and bare PS/2 protocol, and avoid other extended protocols, such as Synaptics, ALPS, etc. Reviewed-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Pali Rohár <pali.rohar@gmail.com> Tested-by: Marcin Sochacki <msochacki+kernel@gmail.com> Tested-by: Till <till2.schaefer@uni-dortmund.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

In preparation of limiting protocols that we try on pass-through ports, let's rework initialization code and factor common code into psmouse_try_protocol() that accepts protocol type (instead of detec() function pointer) and can, for most protocols, perform both detection and initialization. Note that this removes option of forcing Lifebook protocol on devices that are not recognized by lifebook_detect() as having the hardware, but I do not recall anyone using this option.

2015-12-17Input: psmouse - clean up Cypress probeDmitry Torokhov
When Cypress protocol support is disabled cypress_init() is a stub that always returns -ENOSYS, so there is not point in testing for CONFIG_MOUSE_PS2_CYPRESS after we decided that we are dealing with a Cypress device. Also, we should only be calling cypress_detect() when set_properties argument is "true", like with other protocols. There is a slight change in behavior to make follow-up patches more uniform: when we detect Cypress but its initialization fails, instead of immediately returning PSMOUSE_PS2 protocol we now continue trying IntelliMouse [Explorer]. Given that Cypress devices only have issue with Sentelic probes probing Imtellimouse should be safe.

2015-12-15Input: elan_i2c - set input device's vendor and product IDsCharlie Mooney
Previously the "vendor" and "product" IDs for the elan_i2c driver simply reported 0000. This patch modifies the elan_i2c driver to include the Elan vendor ID and the touchpad's product id under input/input*/{vendor,product}. Specifically, this is to allow us to apply a generic Elan gestures config that will apply to all Elan touchpads on ChromeOS. These configs match to input devices in various ways, but one major way is by matching on vendor ID. Adding this patch allows the default Elan touchpad config to be applied to Elan touchpads in this kernel by matching on devices that have vendor ID 04f3. Note that product ID is also available via custom sysfs entry "product_id" as well.

2015-10-26Input: alps - only the Dell Latitude D420/430/620/630 have separate stick ↵Hans de Goede
button bits commit 92bac83dd79e ("Input: alps - non interleaved V2 dualpoint has separate stick button bits") assumes that all alps v2 non-interleaved dual point setups have the separate stick button bits. Later we limited this to Dell laptops only because of reports that this broke things on non Dell laptops. Now it turns out that this breaks things on the Dell Latitude D600 too. So it seems that only the Dell Latitude D420/430/620/630, which all share the same touchpad / stick combo, have these separate bits. This patch limits the checking of the separate bits to only these models fixing regressions with other models.

2015-08-26Input: synaptics - fix handling of disabling gesture modeDmitry Torokhov
Bit 2 of the mode byte has dual meaning: it can disable reporting of gestures when touchpad works in Relative mode or normal Absolute mode, or it can enable so called Extended W-Mode when touchpad uses enhanced Absolute mode (W-mode). The extended W-Mode confuses our driver and causes missing button presses on some Thinkpads (x250, T450s), so let's make sure we do not enable it. Also, according to the spec W mode "... bit is defined only in Absolute mode on pads whose capExtended capability bit is set. In Relative mode and in TouchPads without this capability, the bit is reserved and should be left at 0.", so let's make sure we respect this requirement as well.
