Input: libps2 - attach ps2dev instances as serio port's drvdata

2023-05-18T18:40:32+00:00

In preparation of having unified interrupt handler for PS/2 devices, instead of attaching instances of psmouse and atkbd structures as serio's driver data, switch to attaching ps2dev instances.

Input: trackpoint - combine calls to ps2_command()

2018-02-03T00:51:32+00:00

We do not need to call ps2_command() several times in a row, transmitting every byte as it were a command byte, we can often pack it all in a single command. Also, now that ps2_command() handles retransmission, we do not need to do it ourselves in trackpoint_power_on_reset(). Signed-off-by: Dmitry Torokhov

Input: trackpoint - only expose supported controls for Elan, ALPS and NXP

2018-01-23T00:24:36+00:00

The newer trackpoints from ALPS, Elan and NXP implement a very limited subset of extended commands and controls that the original trackpoints implemented, so we should not be exposing not working controls in sysfs. The newer trackpoints also do not implement "Power On Reset" or "Read Extended Button Status", so we should not be using these commands during initialization. While we are at it, let's change "unsigned char" to u8 for byte data or bool for booleans and use better suited error codes instead of -1. Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov

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

2018-01-23T00:23:17+00:00

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.

Input: trackpoint - add new trackpoint firmware ID

2017-08-19T00:04:11+00:00

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: trackpoint - assume 3 buttons when buttons detection fails

2017-07-19T00:28:47+00:00

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.
