commit 1d9f26262aef6d63ff65eba0fd5f1583f342b69b upstream Properly handle version of the protocol where standard PS/2 packets from trackpoint are stuffed into middle (byte 3-6) of the standard ALPS packets when both the touchpad and trackpoint are used together. The patch is based on work done by Matthew Chapman and additional research done by David Kubicek and Erik Osterholm: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/296610 Many thanks to David Kubicek for his efforts in researching fine points of this new version of the protocol, especially interaction between pad and stick in these models.

commit 5f5eeff4c93256ee93435a3bf08cf18c45e9a994 upstream. Apparently some of Toshiba Protege M300 identify themselves as "Portable PC" in DMI so we need to add that to the DMI table as well. We need DMI data so we can automatically lower Synaptics reporting rate from 80 to 40 pps to avoid over-taxing their keyboard controllers.

This patch is needed when the gpio's became available only at late stages, for example, when using i2c gpio expander. Signed-off-by: Saeed Bishara <saeed@marvell.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
This driver supports Synaptics I2C touchpad controller on eXeda mobile device. Unfortunaltely it only works in relative mode and thus is not comaptible with Xorg Synaptics driver.

Synaptics uses anisotropic coordinate system. On some wide touchpads vertical resolution can be twice as high as horizontal which causes unequal sensitivity on x/y directions. Add support for reading the resolution with EVIOCGABS ioctl. Signed-off-by: Tero Saarni <tero.saarni@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
When pressing any button belonging to the touchpoint, the generated click events don't belong to the touchpoint but to the touchpad. This patch fixes this behaviour, the events will be sent via the correct device, so scrolling with touchpoint is possible.

The appletouch driver is prone to reporting multiple fingers when only one is pressing. The appletouch driver queries an array of pressure sensors and counts local maxima in pressure to determine the number of fingers. It just does this on the raw values, so a data stream like: 0 100 250 300 299 300 250 100 0 actually registers as 2 fingers. This patch updates the logic to ignore small dips in pressure that are less than the threshold.

It appears that when the XO touchpad unit resets from ESD, it sends AA AA instead of AA 00, the psmouse-base code handles the case of AA 00 by triggering a serio reconnect for the port, causing a full reprobe of the device. Testing with OFW shows that this is likely to solve the problem, so the attached patch simply expands the existing test to also catch AA AA.

When we get a relative packet from trackpoint (when we deal with touchscreen/trackpoint combo) we should not send events for the device corresponding to touchscreen as it confuses evtouch driver (it looks like it keeps previously reported absolute coordinates and the cursor stays in the same place).
