2010-08-02Input: switch to input_abs_*() access functionsDaniel Mack17-139/+153
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 Torokhov1-29/+37
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>

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.

2010-07-20Input: i8042 - reset keyboard controller wehen resuming from S2RDmitry Torokhov1-24/+41
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.

2010-07-19Input: synaptics - set min/max for finger widthChris Bagwell1-1/+1
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 Bagwell1-2/+6
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 Rydberg2-43/+96
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 Fritz1-44/+63
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 Gustschin1-37/+135
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.

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.

2010-06-23Input: evdev - never leave the client buffer empty after writeHenrik Rydberg1-3/+7
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.
