2010-05-04tegra kbc: Fixing android boot if key is kept press during boot.Laxman Dewangan
Following changes are done: - Created the new workqueue for the kbc scan process. On default workqueue, the msleep() was not causing the schedule() to booting process. - If there is no entry in fifo then wait for the next scan to complete before re-reading the number of entries in the fifo. if there is no entry then rep key released. - Fixed timing calculation and size of the event entry array. - Fixed the debaunce count calculation from debaunce time from odm. Tested on whistler, with normal boot as well as with continous key pressed d the entire boot time.

This is needed to support devices that put non-keyboard buttons in the keyboard matrix. For instance several devices put the trackball button in the keyboard matrix. In this case BTN_MOUSE should be reported from the same input device as REL_X/Y. It is also useful for devices that have multiple logical keyboard in the same matrix. The HTC dream has a menu key on the external keyboard and another menu key on the slide-out keyboard. With a single input device only one of these menu keys can be mapped to KEY_MENU.

Send both fingers using the new multitouch protocol in addition to the old single finger event and second finger ABS_HAT* hack. The new protocol does not specify how to report up events. To make sure the user-space frameworks can generate up events, we send at least one event where ABS_MT_TOUCH_MAJOR is zero before we stop sending events for a finger.

2009-07-24Input: add detailed multi-touch finger data report protocolHenrik Rydberg
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>
2009-07-24Input: allow certain EV_ABS events to bypass all filteringHenrik Rydberg

This driver allows userspace to receive notification when client specified key combinations are pressed. The client opens /dev/keychord and writes a list of keychords for the driver to monitor. The client then reads or polls /dev/keychord for notifications. A client specified ID for the keychord is returned from read() when a keychord press is detected.
