2010-08-05Input: elantech - report position also with 3 fingersÉric Piel
The 6-byte protocol supports reporting the position when three fingers are pressed, exactly like when one finger is pressed. Report this. In addition, it is also distinguishes between 3 and 4 fingers pressed. Signed-off-by: Éric Piel <eric.piel@tremplin-utc.net> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-08-05Input: elantech - discard the first 2 positions on some firmwaresÉric Piel
According to the Dell/Ubuntu driver, what was previously observed as "jumpy cursor" corresponds to the hardware sending incorrect data for the first two reports of a one touch finger. So let's use the same workaround as in the other driver. Also, detect another firmware version with the same behaviour, as in the other driver.

2010-08-02Input: evdev - rearrange ioctl handlingDmitry Torokhov
Split ioctl handling into 3 separate sections: fixed-length ioctls, variable-length ioctls and multi-number variable length handlers. This reduces identation and makes the code a bit clearer. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-08-02Input: dynamically allocate ABS informationDaniel Mack
As all callers are now changed to only use the input_abs_*() access helpers, switching over to dynamically allocated ABS information is easy. This reduces size of struct input_dev from 3152 to 1640 on 64 bit architectures. Signed-off-by: Daniel Mack <daniel@caiaq.de> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-08-02Input: switch to input_abs_*() access functionsDaniel Mack
Change all call sites in drivers/input to not access the ABS axis information directly anymore. Make them use the access helpers instead. Also use input_set_abs_params() when possible. Did some code refactoring as I was on it. Signed-off-by: Daniel Mack <daniel@caiaq.de> Cc: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2010-08-02Input: adp5588-keypad - fix NULL dereference in adp5588_gpio_add()Dmitry Torokhov
The kpad structure is assigned to i2c client via i2s_set_clientdata() at the end of adp5588_probe(), but in adp5588_gpio_add() we tried to access it (via dev_get_drvdata! which is not nice at all) causing an oops. Let's pass pointer to kpad directly into adp5588_gpio_add() and adp5588_gpio_remove() to avoid accessing driver data before it is set up. Also split out building of gpiomap into a separate function to clear the logic. Reported-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2010-07-22Input: adxl34x - fix leak and use after freeDan Carpenter
These are a couple smatch issues. In the original code, if only one of the allocation fails we leak the other variable so we should goto out_free_mem. Also there was a use after free if debugging was enabled and so I moved the kfree() down a line. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-07-21Input: synaptics - relax capability ID checks on newer hardwareDmitry Torokhov
Older firmwares fixed the middle byte of the Synaptics capabilities query to 0x47, but starting with firmware 7.5 the middle byte represents submodel ID, sometimes also called "dash number". Reported-and-tested-by: Miroslav Šulc <fordfrog@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2010-07-20Input: i8042 - reset keyboard controller wehen resuming from S2RDmitry Torokhov
Some laptops, such as Lenovo 3000 N100, require keyboard controller reset in order to have touchpad operable after suspend to RAM. Even if box does not need the reset it should be safe to do so, so instead of chasing after misbehaving boxes and grow DMI tables, let's reset the controller unconditionally.

2010-07-20Input: twl40300-keypad - fix handling of "all ground" rowsDmitry Torokhov
The Nokia RX51 board code (arch/arm/mach-omap2/board-rx51-peripherals.c) defines a key map for the matrix keypad keyboard. The hardware seems to use all of the 8 rows and 8 columns of the keypad, although not all possible locations are used. The TWL4030 supports keypads with at most 8 rows and 8 columns. Most keys are defined with a row and column number between 0 and 7, except KEY(0xff, 2, KEY_F9), KEY(0xff, 4, KEY_F10), KEY(0xff, 5, KEY_F11), which represent keycodes that should be emitted when entire row is connected to the ground. since the driver handles this case as if we had an extra column in the key matrix. Unfortunately we do not allocate enough space and end up owerwriting some random memory.

2010-07-19Input: synaptics - set min/max for finger widthChris Bagwell
Reporting this will allow GUI config apps to correctly scale width sensitive config values (such as palm detect) to correct range. Current user apps are detecting kernels min/max=0/0 and making an assumption that it means 0/16 or 0/15. Synaptics touchpad interface guides show 4/15 are correct values but driver forces to 0 when no fingers on touchpad.

2010-07-19Input: synaptics - only report width on hardware that supports itChris Bagwell
Synaptics devices report fixed value of 5 for finger/palm widths on devices that do not support capability and driver further hardcodes to 5. Stop reporting this fixed value when its not supported since its not useful. This will aid applications so they can better auto-enable support for multi-touch emulation and palm detection logic using finger width only for devices that support width detection. I can find no applications that currently require existence on ABS_TOOL_WIDTH. Since only synaptics and bcm input devices currently support this tool, it seems they must handle it gracefully.

2010-07-15Input: introduce MT event slotsHenrik Rydberg
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.

2010-07-13Input: xpad - remove mouse buttons and axes for dance padsChristoph Fritz
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.

2010-07-03Input: ads7846 - extend the driver for ads7845 controller supportAnatolij Gustschin
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.
