2014-12-29Input: synaptics - use in-kernel tracking for reporting mt dataBenjamin Tissoires2-381/+34
The current code tries to consider all states and transitions to properly detect which finger is attached to which slot. The code is quite huge and difficult to read. If the sensor manages to group the touch points but is not reliable in giving tracking ids, we can simply use the kernel tracking method. Note that it is already used by Cr-48 Chromebooks. Incidentaly, this fixes a bug reported by Peter Hutterer: """ on the Lenovo T440, run: evemu-record /dev/input/event4 | grep BTN_ then put one, two, three, two fingers down when you go from 3 to 2 fingers the driver sends a spurious BTN_TOUCH 0 event: E: 0.000000 0001 014a 0001 # EV_KEY / BTN_TOUCH 1 E: 0.000000 0001 0145 0001 # EV_KEY / BTN_TOOL_FINGER 1 E: 0.770008 0001 0145 0000 # EV_KEY / BTN_TOOL_FINGER 0 E: 0.770008 0001 014d 0001 # EV_KEY / BTN_TOOL_DOUBLETAP 1 E: 1.924716 0001 014d 0000 # EV_KEY / BTN_TOOL_DOUBLETAP 0 E: 1.924716 0001 014e 0001 # EV_KEY / BTN_TOOL_TRIPLETAP 1 .. changing from 3 to 2 fingers now E: 3.152641 0001 014a 0000 # EV_KEY / BTN_TOUCH 0 E: 3.152641 0001 014d 0001 # EV_KEY / BTN_TOOL_DOUBLETAP 1 E: 3.152641 0001 014e 0000 # EV_KEY / BTN_TOOL_TRIPLETAP 0 E: 3.176948 0001 014a 0001 # EV_KEY / BTN_TOUCH 1 quick look in the kernel shows it's caused by hw.z going to 0 for a packet, so probably a firmware bug. either way, it makes it hard to track BTN_TOUCH as signal that at least one finger is down.

Especially, we don't know how to identify the device yet apart from the PNP ID.

2014-12-18Input: alps - v7: fix finger counting for > 2 fingers on clickpadsHans de Goede1-4/+12
Protocol v7 uses the middle / right button bits on clickpads to communicate "location" information of a 3th touch (and possible 4th) touch on clickpads. Specifically when 3 touches are down, if one of the 3 touches is in the left / right button area, this will get reported in the middle / right button bits and the touchpad will still send a TWO type packet rather then a MULTI type packet, so when this happens we must add the finger reported in the button area to the finger count. Likewise we must also add fingers reported this way to the finger count when we get MULTI packets.

2014-12-18Input: alps - v7: sometimes a single touch is reported in mt[1]Hans de Goede1-4/+14
The v7 proto differentiates between a primary touch (with high precision) and a secondary touch (with lower precision). Normally when 2 fingers are down and one is lifted the still present touch becomes the primary touch, but some traces have shown that this does not happen always. This commit deals with this by making alps_get_mt_count() not stop at the first empty mt slot, and if a touch is present in mt[1] and not mt[0] moving the data to mt[0] (for input_mt_assign_slots).

2014-12-18Input: alps - v7: ignore new packetsHans de Goede1-6/+24
NEW packets are send to indicate a discontinuity in the finger coordinate reporting. Specifically a finger may have moved from slot 0 to 1 or vice versa. INPUT_MT_TRACK takes care of this for us. NEW packets have 3 problems: 1) They do not contain middle / right button info (on non clickpads) this can be worked around by preserving the old button state 2) They do not contain an accurate fingercount, and they are typically send when the number of fingers changes. We cannot use the old finger count as that may mismatch with the amount of touch coordinates we've available in the NEW packet 3) Their x data for the second touch is inaccurate leading to a possible jump of the x coordinate by 16 units when the first non NEW packet comes in Since problems 2 & 3 cannot be worked around, just ignore them.

IBM Trackpoints have a feature to compensate for drift by recalibrating themselves periodically. By default, if for 0.5 seconds there is no change in position, it's used as the new zero. This duration is too low. Often, the calibration happens when the trackpoint is in fact being used. IBM's Trackpoint Engineering Specifications show a configuration register that allows changing this duration, rstdft1. Expose it via sysfs among the other settings.

2014-12-07Input: add support for Elan eKTH I2C touchscreensScott Liu3-0/+1284
This driver supports Elan eKTH I2C touchscreen controllers. Note that these are using custom protocol, as opposed to other Elan parts that use HID-over-I2C and are supported by the standard HID-multitouch driver.

2014-12-07Input: gpio_keys - fix warning regarding uninitialized 'irq' variableDmitry Torokhov1-4/+2
Commit f2d347ff70be453e ("Input: gpio_keys - add device tree support for interrupt only keys") caused the following build warning: drivers/input/keyboard/gpio_keys.c: In function 'gpio_keys_probe': drivers/input/keyboard/gpio_keys.c:647:15: warning: 'irq' may be used uninitialized in this function [-Wmaybe-uninitialized] drivers/input/keyboard/gpio_keys.c:622:7: note: 'irq' was declared here Move button->irq initialization into proper branch and get rid of the temporary.
