2010-12-06Input: add input driver for polled GPIO buttonsGabor Juhos4-0/+280
The existing gpio-keys driver can be usable only for GPIO lines with interrupt support. Several devices have buttons connected to a GPIO line which is not capable to generate interrupts. This patch adds a new input driver using the generic GPIO layer and the input-polldev to support such buttons.

2010-11-30Input: synaptics - fix handling of 2-button ClickPadsYan Li1-1/+2
Lenovo S10-3t's ClickPad is a 2-button ClickPad that reports BTN_LEFT and BTN_RIGHT as normal touchpad, unlike the 1-button ClickPad used in HP mini 210 that reports solely BTN_MIDDLE. In 0xc0-cap response, the 1-button ClickPad has the 20-bit set while 2-button ClickPad has the 8-bit set. This patch makes the kernel only handle 1-button ClickPad specially, and treat 2-button ClickPad in the same fashion as regular touchpads. This fixes kernel bug #18122 and MeeGo bug #4807.

2010-11-20Input: serio HIL MLC - don't deref null, don't leak and return proper errorJesper Juhl2-9/+14
While reviewing various users of kernel memory allocation functions I came across drivers/input/serio/hil_mlc.c::hil_mlc_register() and noticed that: - it calls kzalloc() but fails to check for a NULL return before use. - it makes several allocations and if one fails it doesn't free the previous ones. - It doesn't return -ENOMEM in the failed memory allocation case (it just crashes). This patch corrects all of the above and also reworks the only caller of this function that I could find (drivers/input/serio/hp_sdc_mlc.c::hp_sdc_mlc_out()) so that it now checks the return value of hil_mlc_register() and properly propagates it on failure and I also restructured the code to remove some labels and goto's to make it, IMHO nicer to read.

As pointed out by Oliver Neukum: xpad->irq_in is currently submitted before xpad->bulk_out is allocated. That however is a race, because the callback for irq_in can call xpad360w_process_packet(), which will in turn submit the bulk URB. This patch moves initialization for xpad->bulk_out earlier, so we can ensure xpad->bulk_out is initialized before submitting urb.

2010-11-11Input: hgpk - extend jumpiness detectionDaniel Drake2-20/+88
In addition to forcing recalibrations upon detection of cursor jumps (and performing them quicker than before), detect and discard errant 'jump' packets caused by a firmware bug, which are then repeated with each one being approximately half the delta of the one previously (as if it is averaging out) Based on original work by Paul Fox.

2010-11-11Input: hgpk - rework spew detectionDaniel Drake2-32/+103
The old implementation of spew detection simply tracked the overall position delta of the cursor over every 100 packets. We found that this causes occasional false positives in spew detection, and also that the conditions of the spewy packets are perhaps more fixed than we once thought. Rework the spew detection to look for packets of specific small delta, and only recalibrating if the overall movement delta stays within expected bounds. Also discard duplicate packets in the advanced mode, which appear to be very common. If we don't, the spew detection kicks in far too early. If we get a large spew of duplicates, request a recalibration straight up. Based on earlier work by Paul Fox.

2010-11-11Input: hgpk - support GlideSensor and PenTablet modesDaniel Drake3-43/+441
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.

2010-11-11Input: do not pass injected events back to the originating handlerDmitry Torokhov1-11/+26
Sometimes input handlers (as opposed to input devices) have a need to inject (or re-inject) events back into input core. For example sysrq filter may want to inject previously suppressed Alt-SysRq so that user can take a screen print.

It is not allowed to call input_free_device() after calling input_unregister_device() because input devices are refcounted and unregister will free the device if we were holding he last referenc. The preferred style in input/ is to make input_register_device() the last function in the probe which can fail. That way we don't need to call input_unregister_device().

2010-11-04Input: atkbd - add 'terminal' parameter for IBM Terminal keyboardsBenjamin LaHaise1-1/+11
Many of the IBM Terminal keyboards from the 1980s and early 1990s communicate using a protocol similar, but not identical to the AT keyboard protocol. (Models known to be like this include 6110344, 6110668, 1390876, 1386887, and possibly others.) When the connector is rewired or adapter to an AT-DIN or PS/2 connector, they can be connected to a standard PC, with three caveats: a) They can only use scancode set 3; requests to use anything else are quietly ignored. b) The AT Command to request Make, Break and Repeat codes is not properly interpreted. c) The top function keys on a 122 key keyboard, and the arrow/edit keys in the middle of the board send non-standard scancodes. C) is easily taken care of in userspace, by use of setkeycodes B) can be taken care of by a userspace hack (that makes the kernel complain in dmesg) A) is fixable in theory, but on the keyboard i tested on (6110668), it seems to be detected unoverridably as Set 2, causing userspace oddities that make it harder to fix C). Enclosed is a small patch to the kernel that fixes A) and B) in the kernel, making it much easier to fix C) in userspace. It adds a single kernel command line parameter that overrides the detection that sets these boards as set 2, and instead of sending the Make-break-repeat command to the keyboard, it sends the make-break command, which is properly recognized by these keyboards. Software level key repeating seems to make up for the lack of hardware repeat codes perfectly. Without manually setting the command line parameter (tentatively named atkbd.terminal), this code has no effect, and the driver works exactly as before.
