Input: psmouse - add small delay for IBM trackpoint pass-through mode

2015-12-03T04:25:32+00:00

[ Upstream commit 66bc2f51ef7deabc8b8f3baa98ae64b65e5e973a ] There are trackpoint devices that fail to respond to the PS2 command PSMOUSE_CMD_GETID if immediately queried after the parent device is deactivated. Add a small delay for the hardware to get in a sane state before sending any PS2 commands. One example of such a system is: Lenovo ThinkPad X120e, model 30515QG synaptics: Touchpad model: 1, fw: 8.0, id: 0x1e2b1, caps: 0xd001a3/0x940300/0x121c00, board id: 1811, fw id: 797391 Signed-off-by: Stefan Assmann Signed-off-by: Dmitry Torokhov Signed-off-by: Sasha Levin

Input: psmouse - remove unneeded check in psmouse_reconnect()

2014-10-28T18:42:56+00:00

psmouse_reconnect() will not be called if psmouse driver is not bound to the serio port, so there is no point in checking that. Also, as coded, it introduces potential NULL dereference in psmouse_dbg() in case psmouse is indeed NULL. Let's just remove it. Detected by Coverity: CID 146528 Signed-off-by: Dmitry Torokhov

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

Input: psmouse - add psmouse_matches_pnp_id helper function

2014-09-13T00:30:44+00:00

The matches_pnp_id function from the synaptics driver is useful for other drivers too. Make it a generic psmouse helper function. Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov

Input: add missing POINTER / DIRECT properties to a bunch of drivers

2014-09-08T21:58:12+00:00

I've not done a full audit of all mouse drivers, I noticed these ones were missing the POINTER property while working on the POINTING_STICK property. Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov

Input: add support for Cypress PS/2 Trackpads

Input: psmouse - allow drivers to use psmouse_{de,}activate

Other drivers duplicate this code; no sense in having it be private to psmouse-base. Signed-off-by: Andres Salomon Signed-off-by: Dmitry Torokhov

module_param: make bool parameters really bool (drivers & misc)

2012-01-12T23:02:20+00:00

module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab Signed-off-by: Rusty Russell
