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.

Dance pads don't have any axes/sticks, only buttons for directions. For example buttons like left+right will get triggered at once, an axis can't handle this anyway. So this patch adds a module parameter named "sticks_to_null" for unknown devices. A known dance pad makes use of it by changing to a new mapping-option named DANCEPAD_MAP_CONFIG. Other tested devices may follow by adding this mapping-option too. Some buttons of xpad-devices are addressing mouse-buttons instead of gamepad-buttons. This gets fixed too.

ADS7845 is a controller for 5-wire touch screens and somewhat different from 7846. It requires three serial communications to accomplish one complete conversion. Unlike 7846 it doesn't allow Z1-/Z2- position measurement. The patch extends the ads7846 driver to also support ads7845. The packet struct is extended to contain needed command and conversion buffers. ads7846_rx() and ads7846_rx_val() now differentiate between 7845 and 7846 case. ads7846_probe() is modified to setup ads7845 specific command and conversion messages and to switch ads7845 into power-down mode, since this is needed to be prepared to respond to pendown interrupts.

gpiolib now has debounce support added in .35, so let's make use of it. This allows to use hardware GPIO debouncing on some platforms like OMAP. In case gpiolib debounce setup fails for some GPIO, the driver will fall back to timer based debouncing, which is what it used before.

A column or row configured as a GPI can be programmed to be part of the key event table and therefore also capable of generating a key event interrupt. A key event interrupt caused by a GPI follows the same process flow as a key event interrupt caused by a key press. GPIs configured as part of the key event table allow single key switches and other GPI interrupts to be monitored. As part of the event table, GPIs are represented by the decimal value 97 (0x61 or 1100001) through the decimal value 114 (0x72 or 1110010). See table below for GPI event number assignments for rows and columns. GPI Event Number Assignments for Rows Row0 Row1 Row2 Row3 Row4 Row5 Row6 Row7 97 98 99 100 101 102 103 104 GPI Event Number Assignments for Cols Col0 Col1 Col2 Col3 Col4 Col5 Col6 Col7 Col8 Col9 105 106 107 108 109 110 111 112 113 114 Signed-off-by: NXiaolong Chen <xiao-long.chen@motorola.com> Signed-off-by: NYuanbo Ye <yuan-bo.ye@motorola.com> Signed-off-by: NTao Hu <taohu@motorola.com> Acked-by: NMichael Hennerich <michael.hennerich@analog.com> Signed-off-by: NDmitry Torokhov <dtor@mail.ru>

When the client buffer is very small and wraps around a lot, it may well be that a write increases the head such that head == tail. If this happens between the point where a poll is triggered and the actual data is being read, there will be no data to read. This is confusing to applications, which might end up closing the file. This patch solves the problem by making sure the client buffer is never empty after writing to it. Signed-off-by: NHenrik Rydberg <rydberg@euromail.se> Signed-off-by: NDmitry Torokhov <dtor@mail.ru>

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.
