linux/drivers/input/mouse/psmouse-base.c, branch v3.4.30

Merge commit 'v3.3-rc6' into next

2012-03-09T18:55:17Z

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

2012-02-24T08:55:28Z

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)

2012-01-12T23:02:20Z

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

Input: psmouse - make sure we do not use stale methods

2011-12-30T23:26:36Z

Several protocol initialization routines can fail after they set up psmouse methods, such as reconnect and disconnect. This may lead to these stale methods used with different protocol that they were intended to be used for and may cause unpredictavle behavior and/or crashes. Make sure we start with a clean slate before executing each and every protocol detection and/or initialization routine.

Input: synaptics - add support for Relative mode

2011-11-10T05:23:31Z

Currently, the synaptics driver puts the device into Absolute mode. As explained in the synaptics documentation section 3.2, in this mode, the device sends a continuous stream of packets at the maximum rate to the host when the user's fingers are near or on the pad or pressing buttons, and continues streaming for 1 second afterwards. These packets are even sent when there is no new information to report, even when they are duplicates of the previous packet. For embedded systems this is a bit much - it results in a huge and uninterrupted stream of interrupts at high rate. This patch adds support for Relative mode, which can be selected as a new psmouse protocol. In this mode, the device does not send duplicate packets and acts like a standard PS/2 mouse. However, synaptics-specific functionality is still available, such as the ability to set the packet rate, and rather than disabling gestures and taps at the hardware level unconditionally, a 'synaptics_disable_gesture' sysfs attribute has been added to allow control of this functionality. This solves a long standing OLPC issue: synaptics hardware enables tap to click by default (even in the default relative mode), but we have found this to be inappropriate for young children and first time computer users. Enabling the synaptics driver disables tap-to-click, but we have previously been unable to use this because it also enables Absolute mode, which is too "spammy" for our desires and actually overloads our EC with its continuous stream of packets. Now we can enable the synaptics driver, disabling tap to click while retaining the less noisy Relative mode. Signed-off-by: Daniel Drake Signed-off-by: Dmitry Torokhov

Input: convert obsolete strict_strtox to kstrtox

2011-11-10T05:23:26Z

With commit 67d0a0754455f89ef3946946159d8ec9e45ce33a we mark strict_strtox as obsolete. Convert all remaining such uses in drivers/input/. Also change long to appropriate types, and return error conditions from kstrtox separately, as Dmitry sugguests. Signed-off-by: JJ Ding Signed-off-by: Dmitry Torokhov

Input: psmouse - switch to using dev_*() for messages

2011-10-11T01:28:16Z

This will ensure our reporting is consistent with the rest of the system and we do not refer to obsolete source file names. Reviewed-by: Wanlong Gao Reviewed-by: JJ Ding Reviewed-by: Daniel Kurtz Signed-off-by: Dmitry Torokhov

Input: hgpk - support GlideSensor and PenTablet modes

2010-11-12T06:21:15Z

Add a "hgpk_mode" sysfs attribute that allows selection between 3 options: Mouse (the existing option), GlideSensor and PenTablet. GlideSensor is an enhanced protocol for the regular touchpad mode that additionally reports pressure and uses absolute coordinates. We suspect that it may be more reliable than mouse mode in some environments. PenTablet mode puts the touchpad into resistive mode, you must then use a stylus as an input. We suspect this is the most reliable way to drive the touchpad. The GlideSensor and PenTablet devices expose themselves with the intention of being combined with the synaptics X11 input driver. Based on earlier work by Paul Fox. Signed-off-by: Daniel Drake Signed-off-by: Dmitry Torokhov

Input: serio - support multiple child devices per single parent

2010-10-13T14:49:28Z

Some (rare) serio devices need to have multiple serio children. One of the examples is PS/2 multiplexer present on several TQC STKxxx boards, which connect PS/2 keyboard and mouse to single tty port. Signed-off-by: Dmitry Eremin-Solenikov Signed-off-by: Dmitry Torokhov

param: use ops in struct kernel_param, rather than get and set fns directly

2010-08-11T13:34:13Z

This is more kernel-ish, saves some space, and also allows us to expand the ops without breaking all the callers who are happy for the new members to be NULL. The few places which defined their own param types are changed to the new scheme (more which crept in recently fixed in following patches). Since we're touching them anyway, we change get() and set() to take a const struct kernel_param (which they really are). This causes some harmless warnings until we fix them (in following patches). To reduce churn, module_param_call creates the ops struct so the callers don't have to change (and casts the functions to reduce warnings). The modern version which takes an ops struct is called module_param_cb. Signed-off-by: Rusty Russell Reviewed-by: Takashi Iwai Tested-by: Phil Carmody Cc: "David S.
