i8042 controller present in Dell Vostro V13 errorneously signals spurious timeouts. Introduce i8042.notimeout parameter for ignoring i8042-signalled timeouts and apply this quirk automatically for Dell Vostro V13, based on DMI match. In addition to that, this machine also needs to be added to nomux blacklist. Signed-off-by:

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. Acked-by:

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. Reported-by: Tobyn Bertram Signed-off-by:

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. Acked-by:

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. Acked-by:

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. Tested-by:
