2024-10-01Revert "Input: Add driver for PixArt PS/2 touchpad"Dmitry Torokhov1-12/+0
This reverts commit 740ff03d7238214a318cdcfd96dec51832b053d2 because current PixArt detection is too greedy and claims devices that are not PixArt.

2024-07-23Input: Add driver for PixArt PS/2 touchpadBinbin Zhou1-0/+12
This patch introduces a driver for the PixArt PS/2 touchpad, which supports both clickpad and touchpad types. At the same time, we extended the single data packet length to 16, because according to the current PixArt hardware and FW design, we need 11 bytes/15 bytes to represent the complete three-finger/four-finger data.

2024-01-18Input: navpoint - remove driverDuje Mihanović1-12/+0
This driver does not use the SPI core as it should, instead tampering with the SSP registers manually. Refactoring the driver is almost certainly not worth it as the hardware seems to have been designed for and used only in the HP iPAQ hx4700 removed more than a year ago in d6df7df7ae5a ("ARM: pxa: remove unused board files"), so let's remove it.

2018-05-23Input: elantech - add support for SMBus devicesBenjamin Tissoires1-0/+12
Many of the Elantech devices are connected through PS/2 and a different bus (SMBus or plain I2C). To not break any existing device, we only enable SMBus based on a module parameter. If some laptops require the quirk to be set, we will have to rely on a list of PNPIds or MDI matching to individually expose those hardware over SMBus. the parameter mentioned above is elantech_smbus from the psmouse module.

2017-03-25Input: synaptics - add support for Intertouch devicesBenjamin Tissoires1-0/+12
Most of the Synaptics devices are connected through PS/2 and a different bus (SMBus or HID over I2C). The secondary bus capability is indicated by the InterTouch bit in extended capability 0x0C. We only enable the InterTouch device to be created for the laptops registered with the top software button property or those we know that are functional. In the future, we might change the default to always rely on the InterTouch bus. Currently, users can enable/disable the feature with the psmouse parameter synaptics_intertouch.

2017-03-25Input: psmouse - add support for SMBus companionsBenjamin Tissoires1-0/+4
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.

2016-01-27Input: byd - add BYD PS/2 touchpad driverChris Diamand1-0/+10
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.

2015-08-04Input: Allow compile test of GPIO consumers if !GPIOLIBGeert Uytterhoeven1-1/+1
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate.

2015-04-14Input: add vmmouse driverThomas Hellstrom1-0/+12
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.

Most of the protocol for these touchpads has been reverse engineered. This commit adds a basic multitouch-capable driver. A lot of the protocol is still unknown. Especially, we don't know how to identify the device yet apart from the PNP ID. The previous workaround for these devices has been left in place in case the driver is not compiled into the kernel or in case some other device with the same PNP ID is not recognized by the driver yet still has the same problems with the device probing code.

2014-05-12Input: fix ps2/serio module dependencyArnd Bergmann1-1/+1
The ps2 mouse and keyboard drivers use the "serio" framework that they correctly select in Kconfig, and that in turn depends on the i8042 driver, which is also allowed to be disabled for architectures that don't have an i8042. However, Kconfig also allows i8042 to be built as a module while the serio framework is built-in, which causes this link error: drivers/built-in.o: In function `ps2_begin_command': :(.text+0x26b6cc): undefined reference to `i8042_check_port_owner' :(.text+0x26b6d4): undefined reference to `i8042_lock_chip' drivers/built-in.o: In function `ps2_end_command': :(.text+0x26b734): undefined reference to `i8042_check_port_owner' :(.text+0x26b73c): undefined reference to `i8042_unlock_chip' On x86, a specific 'select SERIO_I8042' takes care of it, but not on the other architecture that potentially have a i8042. This patch changes the Kconfig logic to ensure that whenever there is an i8042, it does get used for the serio driver, avoiding the link error above.

2011-01-20kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes1-5/+5
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.
