2010-12-16hid: egalax: Add support for Samsung NB30 netbookRichard Nauber3-0/+4
The Samsung NB30 touch has a DWAV dual-touch device. This patch adds the NB30 to the list of supported devices, and grabs it accordingly in hid-core.

2010-12-16hid: egalax: Add support for WetabHenrik Rydberg3-0/+4

2010-12-16hid: egalax: Convert to MT slotsHenrik Rydberg1-63/+23
The firmware in the joojoo reports touches sequentially, one per report, which confuses the current driver. A further complication is the absense of any indication of a touch frame. This patch converts the driver to the MT slots protocol, and outputs one full touch frame per report. This way, proper handling for both firmwares is ensured.

2010-12-16hid: egalax: Report zero as minimum pressureHenrik Rydberg1-0/+1
The firmware reports a logical minimum of one, but in order for userspace applications to correctly map all reported values to non-zero pressure, the driver needs to report a logical minimum of zero.

2010-12-16input: mt: Add hovering distance axisHenrik Rydberg2-2/+10
Touch devices capable of hovering, i.e., fingers detected a distance from the surface, are not supported by the current input MT protocol. This patch adds ABS_MT_DISTANCE, which may be used to indicate the distance between the contact and the surface. Signed-off-by: Henrik Rydberg <[email protected]>
2010-12-16input: mt: Move tracking and pointer emulation to input-mtHenrik Rydberg7-71/+138
The drivers using the type B protocol all report tracking information the same way. The contact id is semantically equivalent to ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates the driver. The situation can be improved upon by providing a common pointer emulation code, thereby removing the need for the tracking id in the driver. This patch moves all tracking event handling over to the input core, simplifying both the existing drivers and the ones currently in preparation.

2010-12-14Input: define separate EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2Dmitry Torokhov2-57/+62
The desire to keep old names for the EVIOCGKEYCODE/EVIOCSKEYCODE while extending them to support large scancodes was a mistake. While we tried to keep ABI intact (and we succeeded in doing that, programs compiled on older kernels will work on newer ones) there is still a problem with recompiling existing software with newer kernel headers. New kernel headers will supply updated ioctl numbers and kernel will expect that userspace will use struct input_keymap_entry to set and retrieve keymap data. But since the names of ioctls are still the same userspace will happily compile even if not adjusted to make use of the new structure and will start miraculously fail in the field. To avoid this issue let's revert EVIOCGKEYCODE/EVIOCSKEYCODE definitions and add EVIOCGKEYCODE_V2/EVIOCSKEYCODE_V2 so that userspace can explicitly select the style of ioctls it wants to employ.

2010-11-30Input: synaptics - fix handling of 2-button ClickPadsYan Li1-1/+2
Lenovo S10-3t's ClickPad is a 2-button ClickPad that reports BTN_LEFT and BTN_RIGHT as normal touchpad, unlike the 1-button ClickPad used in HP mini 210 that reports solely BTN_MIDDLE. In 0xc0-cap response, the 1-button ClickPad has the 20-bit set while 2-button ClickPad has the 8-bit set. This patch makes the kernel only handle 1-button ClickPad specially, and treat 2-button ClickPad in the same fashion as regular touchpads. This fixes kernel bug #18122 and MeeGo bug #4807.

2010-11-20Input: serio HIL MLC - don't deref null, don't leak and return proper errorJesper Juhl2-9/+14
While reviewing various users of kernel memory allocation functions I came across drivers/input/serio/hil_mlc.c::hil_mlc_register() and noticed that: - it calls kzalloc() but fails to check for a NULL return before use. - it makes several allocations and if one fails it doesn't free the previous ones. - It doesn't return -ENOMEM in the failed memory allocation case (it just crashes). This patch corrects all of the above and also reworks the only caller of this function that I could find (drivers/input/serio/hp_sdc_mlc.c::hp_sdc_mlc_out()) so that it now checks the return value of hil_mlc_register() and properly propagates it on failure and I also restructured the code to remove some labels and goto's to make it, IMHO nicer to read.

As pointed out by Oliver Neukum: xpad->irq_in is currently submitted before xpad->bulk_out is allocated. That however is a race, because the callback for irq_in can call xpad360w_process_packet(), which will in turn submit the bulk URB.

Disable the recalibration guard where new recalibrations are triggered if we detect a packet too soon after calibrating - we found that this results in erroneous recalibrations, and if the recalibration failed then the rest of our badness-detection code will request another.

2010-11-11Input: hgpk - rework spew detectionDaniel Drake2-32/+103
The old implementation of spew detection simply tracked the overall position delta of the cursor over every 100 packets. We found that this causes occasional false positives in spew detection, and also that the conditions of the spewy packets are perhaps more fixed than we once thought. Rework the spew detection to look for packets of specific small delta, and only recalibrating if the overall movement delta stays within expected bounds. Also discard duplicate packets in the advanced mode, which appear to be very common. If we don't, the spew detection kicks in far too early. If we get a large spew of duplicates, request a recalibration straight up. Based on earlier work by Paul Fox.

Add a "hgpk_mode" sysfs attribute that allows selection between 3 options: Mouse (the existing option), GlideSensor and PenTablet. GlideSensor is an enhanced protocol for the regular touchpad mode that additionally reports pressure and uses absolute coordinates. We suspect that it may be more reliable than mouse mode in some environments. PenTablet mode puts the touchpad into resistive mode, you must then use a stylus as an input. We suspect this is the most reliable way to drive the touchpad. The GlideSensor and PenTablet devices expose themselves with the intention of being combined with the synaptics X11 input driver.
