2010-09-09Input: add support for large scancodesMauro Carvalho Chehab1-11/+44
Several devices use a high number of bits for scancodes. One important group is the Remote Controllers. Some new protocols like RC-6 define a scancode space of 64 bits. The current EVIO[CS]GKEYCODE ioctls allow replace the scancode/keycode translation tables, but it is limited to up to 32 bits for scancode. Also, if userspace wants to clean the existing table, replacing it by a new one, it needs to run a loop calling the ioctls over the entire sparse scancode space. To solve those problems, this patch extends the ioctls to allow drivers handle scancodes up to 32 bytes long (the length could be extended in the future should such need arise) and allow userspace to query and set scancode to keycode mappings not only by scancode but also by index. Compatibility code were also added to handle the old format of EVIO[CS]GKEYCODE ioctls. Folded fixes by: - Dan Carpenter: locking fixes for the original implementation - Jarod Wilson: fix crash when setting keycode and wiring up get/set handlers in original implementation. - Dmitry Torokhov: rework to consolidate old and new scancode handling, provide options to act either by index or scancode.

2010-07-15Input: introduce MT event slotsHenrik Rydberg1-0/+33
With the rapidly increasing number of intelligent multi-contact and multi-user devices, the need to send digested, filtered information from a set of different sources within the same device is imminent. This patch adds the concept of slots to the MT protocol. The slots enumerate a set of identified sources, such that all MT events can be passed independently and selectively per identified source. The protocol works like this: Instead of sending a SYN_MT_REPORT event immediately after the contact data, one sends an ABS_MT_SLOT event immediately before the contact data. The input core will only emit events for slots with modified MT events. It is assumed that the same slot is used for the duration of an initiated contact.

2010-06-23Input: evdev - use driver hint to compute size of event bufferHenrik Rydberg1-0/+21
Some devices, in particular MT devices, produce a lot of data. This may lead to overflowing of the event queues in evdev driver, which by default are fairly small. Let the drivers hint the average number of events per packet generated by the device, and use that information when computing the buffer size evdev should use for the device.

2010-04-13Input: add Analog Devices AD714x captouch input driverBryan Wu1-0/+1
AD7142 and AD7147 are integrated capacitance-to-digital converters (CDCs) with on-chip environmental calibration for use in systems requiring a novel user input method. The AD7142 and AD7147 can interface to external capacitance sensors implementing functions such as buttons, scrollwheels, sliders, touchpads and so on. The chips don't restrict the specific usage. Depending on the hardware connection, one special target board can include one or several these components. The platform_data for the device's "struct device" holds these information. The data-struct defined in head file descript the hardware feature of button/scrollwheel/slider/touchpad components on target boards, which need be filled in the arch/mach-/. As the result, the driver is independent of boards. It gets the components layout from the platform_data, registers related devices, fullfills the algorithms and state machines for these components and report related input events to up level.

Now that the driver has been switched to use unsigned short keycodes instead of unsigned char we can release this range back into pull. We keep code 255 (ATKBD_KEY_NULL) reserved since users may have been using it to silence keys they do not care about since atkbd silently drops scancodes mapped to this keycode.

2010-02-18Input: add KEY_RFKILLMatthew Garrett1-0/+1
Most laptops have keys that are intended to toggle all device state, not just wifi. These are currently generally mapped to KEY_WLAN. As a result, rfkill will only kill or enable wifi in response to the key press. This confuses users and can make it difficult for them to enable bluetooth and wwan devices. This patch adds a new keycode, KEY_RFKILL. It indicates that the system should toggle the state of all rfkillable devices.

2010-01-30Input: implement input filtersDmitry Torokhov1-0/+8
Sometimes it is desirable to suppress certain events from reaching input handlers and thus user space. One such example is Mac mouse button emulation code which catches certain key presses and converts them into button clicks as if they were emitted by a virtual mouse. The original key press events should be completely suppressed, otherwise user space will be confused, and while keyboard driver does it on its own evdev is blissfully unaware of this arrangement. This patch adds notion of 'filter' to the standard input handlers, which may flag event as filtered thus preventing it from reaching other input handlers. Filters don't (nor will they ever) have a notion of priority relative to each other, input core will run all of them first and any one of them may mark event as filtered. This patch is inspired by similar patch by Matthew Garret but the implementation and intended usage are quite different. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2010-01-04HID: handle joysticks with large number of buttonsJiri Kosina1-0/+42
Current HID code doesn't properly handle HID joysticks which have larger number of buttons than what fits into current range reserved for BTN_JOYSTICK. One such joystick reported to not work properly is Saitek X52 Pro Flight System. We can't extend the range to fit more buttons in, because of backwards compatibility reasons. Therefore this patch introduces a new BTN_TRIGGER_HAPPY range, and uses these to map the buttons which are over BTN_JOYSTICK limit.

There are a few multi-touch devices that support finger tracking well in hardware, Stantum being the prime example.

2009-04-28Input: add detailed multi-touch finger data report protocolHenrik Rydberg1-0/+23
In order to utilize the full power of the new multi-touch devices, a way to report detailed finger data to user space is needed. This patch adds a multi-touch (MT) protocol which allows drivers to report details for an arbitrary number of fingers. The driver sends a SYN_MT_REPORT event via the input_mt_sync() function when a complete finger has been reported. In order to stay compatible with existing applications, the data reported in a finger packet must not be recognized as single-touch events. In addition, all finger data must bypass input filtering, since subsequent events of the same type refer to different fingers. A set of ABS_MT events with the desired properties are defined. The events are divided into categories, to allow for partial implementation. The minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked. If the device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide the size of the approaching finger. Anisotropy and direction may be specified with ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and ABS_MT_ORIENTATION. Devices with more granular information may specify general shapes as blobs, i.e., as a sequence of rectangular shapes grouped together by a ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE may be used to specify whether the touching tool is a finger or a pen. Signed-off-by: Henrik Rydberg <rydberg@euromail.se> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2009-04-28Input: bcm5974 - add quad-finger tappingHenrik Rydberg1-0/+1
The integrated button on the new unibody Macbooks presents a need to report explicit four-finger actions. Evidently, the finger pressing the button is also touching the trackpad, so in order to fully support three-finger actions, the driver must be able to report four-finger actions. This patch adds a new button, BTN_TOOL_QUADTAP, which achieves this. Signed-off-by: Henrik Rydberg <rydberg@euromail.se> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
