OLPC has switched to a Synaptics touchpad. It turns out that it's pretty useless in absolute mode.

2010-12-22Input: synaptics - ignore bogus mt packetHenrik Rydberg
In multitouch mode, at least one device (fw: 7.4 id: 0x1c0b1) sometimes sends a final main packet with x == 1. Since the normal values are above 1472, this is clearly bogus. At the same time, a two-finger touch is signaled, even though only one finger was on the pad to begin with. This patch ignores the packet altogether, removing the problem.

2010-12-21Input: synaptics - add multi-finger and semi-mt supportHenrik Rydberg
The Synaptics 2.7 series of touchpads support a mode for reporting two sets of X/Y/Pressure data (advanced gesture mode). By default, these devices report only single finger data, depriving userspace of the nowadays ubiquitous two-finger scroll gesture. Enabling advanced gesture mode also enables the multi-finger report, although the device does not claim that capability. Up to three fingers can be reported this way. While two or three fingers are touching, the normal packet is prepended by a reduced finger packet of lower resolution. From the two packets (which do not represent the actual fingers), the bounding rectangle of the individual contacts can be extracted. This information is sufficient to perform scaling gestures and a limited form of rotation gesture. The behavior has been coined semi-mt capability, and is signaled to userspace via the INPUT_PROP_SEMI_MT device property. Work to decode the advanced gesture packet: Takashi Iwai. Cleanup and testing of the original patch: Chase Douglas. Minor cleanup and testing: Chris Bagwell. Finalization and semi-mt support: Henrik Rydberg.

2010-12-20Input: fix double equality sign in ueventHenrik Rydberg
Looking at the uevent stream for input devices, all properties are on the form "A=B" except the bitmap values, which are on the form "A==B". This bug has been around at least since 2007, and the input uevent code has been untouched since. The recent addition of device properties suggests this is a good time for a remedy.

2010-12-20Input: introduce device propertiesHenrik Rydberg
Today, userspace sets up an input device based on the data it emits. This is not always enough; a tablet and a touchscreen may emit exactly the same data, for instance, but the former should be set up with a pointer whereas the latter does not need to. Recently, a new type of touchpad has emerged where the buttons are under the pad, which changes logic without changing the emitted data. This patch introduces a new ioctl, EVIOCGPROP, which enables user access to a set of device properties useful during setup. The properties are given as a bitmap in the same fashion as the event types, and are also made available via sysfs, uevent and /proc/bus/input/devices.

2010-12-16hid: egalax: Convert to MT slotsHenrik Rydberg
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.

2010-12-16input: mt: Add hovering distance axisHenrik Rydberg

2010-12-16input: mt: Move tracking and pointer emulation to input-mtHenrik Rydberg
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 Torokhov
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.

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.
