2015-03-24Input: of_touchscreen - register multitouch axesMaxime Ripard1-5/+17
So far, the DT parsing code was only setting up the regular input axes, completely ignoring their multitouch counter parts. Fill them with the same parameters than the regular axes.

2015-03-11Input: elants_i2c - append hw_version to FW fileCharlie Mooney1-4/+10
Currently the elants_i2c driver simply requests a static filename /lib/firmware/elants_i2c.bin when it gets firmware updates. This is a problem if you have two Elan touchscreens using the same driver. If both touchscreens have different firmwares, you would need to move the files around in your filesystem when you're updating them so that they don't get updated with the other's FW. If you have a read-only filesystem then this is impossible, even. This patch changes the elants_i2c driver to automatically append the four-hex-digit hw_version of the device onto the name of the FW file it's requesting for update. Since different touchscreens should have a different hw_version's this means the user needs to append the hw version of the touchscreen he or she intends to update onto the end of the firmware filename and then the driver will do the rest. The firmware filenames it looks for now are of the form: elants_i2c_${HW_VERSION}.bin eg: elants_i2c_2a44.bin Signed-off-by: Charlie Mooney <charliemooney@chromium.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

The 2015 series of the Lenovo thinkpads added back the hardware buttons on top of the touchpad for the trackstick. Unfortunately, they are wired to the touchpad, and not the trackstick. Thus, they are seen as extra buttons from the kernel point of view. This leads to a problem in user space because extra buttons on synaptics devices used to be used as scroll up/down buttons. So in the end, the experience for the user is scroll events for buttons left and right when using the trackstick. Yay! Fortunately, the firmware advertises such behavior in the extended capability $10, and so we can re-route the buttons through the pass-through interface.

The 2015 series of the Lenovo thinkpads added back the hardware buttons on top of the touchpad for the trackstick. Unfortunately, Lenovo used the PNPIDs that are supposed to be "5 buttons" touchpads, so the new laptops also have the INPUT_PROP_TOPBUTTONPAD. Yay! Instead of manually removing each of the new ones, or hoping that we know all the current ones, we can consider that the PNPIDs list that were given contains touchpads that have the trackstick buttons, either physically wired to them, or emulated with the top software button property. Thanks to the extra buttons capability in query $10, we can reliably detect the physical buttons from the software ones, and so we can remove the TOPBUTTONPAD property even if it was declared as such.

2015-03-09Input: synaptics - split synaptics_resolution(), query firstDaniel Martin1-12/+23
Split the function synaptics_resolution() into synaptics_resolution() and synaptics_quirks(). synaptics_resolution() will be called before synaptics_quirks() to query dimensions and resolutions before overwriting them with quirks.

2015-03-09Input: sun4i-ts - A10 (sun4i) has a different temperature curveHans de Goede1-3/+13
Testing has revealed that the temperature in the rtp controller of the A10 (sun4i) SoC has a different curve then on the A13 (sun5i) and later models. Add a new sun5i-a13-ts compatible to differentiate the newer models and set the curve based on the compatible string. The new curve is still not ideal on all A10-s, that seems to have to do with there being a large spread between different A10-s out there, the new curve us based on callibration results on 4 completely different models: raw min raw max temp min temp max stepsize offset Tong Zhang's hackberry 2402 2680 45.0 80.0 0.125 -255.3 Hansg's Cubieboard 2207 2300 36.0 45.0 0.096 -175.8 Olliver's lime 1 (*): 2258 2537 48.3 87.1 0.139 -265.7 Olliver's lime 2 (*): 2222 2486 46.7 91.7 0.170 -331.0 *) from: http://linux-sunxi.org/Temperature_Calibration Average all 4: 0.133 -257.0 Average without outliers (middle 2): 0.132 -261.0 Since it is better to slightly overreport the temperature this patch uses the average of all 4 as curve. This fixes the temperature reported on the A10 being much higher then expected.

2015-03-08Input: psmouse - disable "palm detection" in the focaltech driverMathias Gottschlag1-10/+0
Apparently, the threshold for large contact area seems to be rather low on some devices, causing the touchpad to frequently freeze during normal usage. Because we do now know how we are supposed to use the value in question, this commit just drops the related code completely.

2015-03-08Input: psmouse - disable changing resolution/rate/scale for FocalTechMathias Gottschlag3-1/+44
These PS/2 commands make some touchpads stop responding, so this commit adds some dummy functions to replace the generic implementation. Because scale changes were not encapsulated in a method of struct psmouse yet, this commit adds a method set_scale to psmouse.

2015-03-08Input: psmouse - ensure that focaltech reports consistent coordinatesMathias Gottschlag1-2/+10
We don't know whether x_max or y_max really hold the maximum possible coordinates, and we don't know for sure whether we correctly interpret the coordinates sent by the touchpad, so we clamp the reported values to prevent confusion in userspace code.
