Input: elan_i2c - clear INT before resetting controller

2018-05-23T01:36:26Z

[ Upstream commit 4b3c7dbbfff0673e8a89575414b864d8b001d3bb ] Some old touchpad FWs need to have interrupt cleared before issuing reset command after updating firmware. We clear interrupt by attempting to read full report from the controller, and discarding any data read. Signed-off-by: KT Liao Signed-off-by: Dmitry Torokhov Signed-off-by: Sasha Levin

Input: elan_i2c - check if device is there before really probing

[ Upstream commit c5928551fd41b2eecdad78fa2be2a4a13ed5fde9 ] Before trying to properly initialize the touchpad and generate bunch of errors, let's first see it there is anything at the given address. If we get error, fail silently with -ENXIO. Reviewed-by: Guenter Roeck Signed-off-by: Dmitry Torokhov Signed-off-by: Sasha Levin

Input: trackpoint - force 3 buttons if 0 button is reported

[ Upstream commit f5d07b9e98022d50720e38aa936fc11c67868ece ] Lenovo introduced trackpoint compatible sticks with minimum PS/2 commands. They supposed to reply with 0x02, 0x03, or 0x04 in response to the "Read Extended ID" command, so we would know not to try certain extended commands. Unfortunately even some trackpoints reporting the original IBM version (0x01 firmware 0x0e) now respond with incorrect data to the "Get Extended Buttons" command: thinkpad_acpi: ThinkPad BIOS R0DET87W (1.87 ), EC unknown thinkpad_acpi: Lenovo ThinkPad E470, model 20H1004SGE psmouse serio2: trackpoint: IBM TrackPoint firmware: 0x0e, buttons: 0/0 Since there are no trackpoints without buttons, let's assume the trackpoint has 3 buttons when we get 0 response to the extended buttons query.

[ Upstream commit 293b915fd9bebf33cdc906516fb28d54649a25ac ] Trackpoint buttons detection fails on ThinkPad 570 and 470 series, this makes the middle button of the trackpoint to not being recogized. As I don't believe there is any trackpoint with less than 3 buttons this patch just assumes three buttons when the extended button information read fails.

[ Upstream commit ec667683c532c93fb41e100e5d61a518971060e2 ] Synaptics add new TP firmware ID: 0x2 and 0x3, for now both lower 2 bits are indicated as TP. Change the constant to bitwise values. This makes trackpoint to be recognized on Lenovo Carbon X1 Gen5 instead of it being identified as "PS/2 Generic Mouse".

Input: vmmouse - remove port reservation

2016-07-11T00:20:03Z

[ Upstream commit 60842ef8128e7bf58c024814cd0dc14319232b6c ] The VMWare EFI BIOS will expose port 0x5658 as an ACPI resource. This causes the port to be reserved by the APCI module as the system comes up, making it unavailable to be reserved again by other drivers, thus preserving this VMWare port for special use in a VMWare guest. This port is designed to be shared among multiple VMWare services, such as the VMMOUSE. Because of this, VMMOUSE should not try to reserve this port on its own. The VMWare non-EFI BIOS does not do this to preserve compatibility with existing/legacy VMs. It is known that there is small chance a VM may be configured such that these ports get reserved by other non-VMWare devices, and if this ever happens, the result is undefined.
