Input: psmouse - add support for SMBus companions

2017-03-25T17:37:29+00:00

This provides glue between PS/2 devices that enumerate the RMI4 devices and Elan touchpads to the RMI4 (or Elan) SMBus driver. The SMBus devices keep their PS/2 connection alive. If the initialization process goes too far (psmouse_activate called), the device disconnects from the I2C bus and stays on the PS/2 bus, that is why we explicitly disable PS/2 device reporting (by calling psmouse_deactivate) before trying to register SMBus companion device. The HID over I2C devices are enumerated through the ACPI DSDT, and their PS/2 device also exports the InterTouch bit in the extended capability 0x0C. However, the firmware keeps its I2C connection open even after going further in the PS/2 initialization. We don't need to take extra precautions with those device, especially because they block their PS/2 communication when HID over I2C is used.

Input: byd - add BYD PS/2 touchpad driver

2016-01-28T01:27:25+00:00

Driver for the BYD BTP10463 touchpad, found in PC Specialist `Lafite' laptops. This patch sends the magic command sequence which causes the touchpad to stream intellimouse-style packets. Gestures are detected inside the touchpad, and exposed as special values in the Z component of each packet - absolute coordinates are not supported, even in the Windows driver. At present, this supports two-finger vertical and horizontal scrolling, and provides the framework to expose the other gestures it can recognize.

Input: cyapa - add gen6 device module support

2015-07-24T00:34:04+00:00

Based on the cyapa core, add support for basic functionality of the gen6 trackpad devices. The driver can automatically determine what protocol (gen3, gen5, or gen6) should be used with the attached trackpad device. Signed-off-by: Dudley Du Signed-off-by: Dmitry Torokhov

Input: add vmmouse driver

2015-04-14T21:29:03+00:00

VMMouse enables low-latency mouse-cursor-movements for VMWare and QEMU guests. By removing the guest cursor and using the host as a guest cursor the cursor movement appears instant although in reality there is some lag. To be able to do this, the host's view of the cursor position must exactly match the guest's view and an absolute pointer device is needed. Enter the VMMouse. While the VMMouse driver has historically been an Xorg user-space driver, implementing it as a kernel imput driver enables rootless Xorg and new compositing display servers for VMware guests.

Input: cyapa - add gen5 trackpad device basic functions support

2015-01-18T08:10:28+00:00

This change adds support for Gen5 Cypress trackpads. The driver detects generation of the device at probe time and automatically selects appropriate protocol. Signed-off-by: Dudley Du Tested-by: Jeremiah Mahler Signed-off-by: Dmitry Torokhov

Input: cyapa - re-design driver to support multi-trackpad in one driver

2015-01-18T08:10:28+00:00

In order to support multiple different chipsets and communication protocols trackpad devices in one cyapa driver, the new cyapa driver is re-designed with one cyapa driver core and multiple device specific functions component. The cyapa driver core is contained in this patch, it supplies basic functions that working with kernel and input subsystem, and also supplies the interfaces that the specific devices' component can connect and work together with as one driver.

Input: psmouse - add support for detecting FocalTech PS/2 touchpads

2014-09-15T21:30:46+00:00

The Asus X450 and X550 laptops use a PS/2 touchpad from a new manufacturer called FocalTech: https://bugzilla.kernel.org/show_bug.cgi?id=77391 https://bugzilla.redhat.com/show_bug.cgi?id=1110011 The protocol for these devices is not known at this time, but even without knowing the protocol they need some special handling. They get upset by some of our other PS/2 device probing, and once upset generate random mouse events making things unusable even with an external mouse. This patch adds detection of these devices based on their pnp ids, and when they are detected, treats them as a bare ps/2 mouse. Doing things this way they at least work in their ps/2 mouse emulation mode. Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov
