linux/drivers/input/touchscreen, branch v3.0.87

Merge branch 'next' into for-linus

2011-05-24T07:06:26Z

Input: tsc2007 - add X, Y and Z fuzz factors to platform data

2011-05-17T16:38:53Z

These new platform-specific values can be used to set the fuzz parameter passed to the input_set_abs_params() function for the ABS_X, ABS_Y and ABS_PRESSURE axes. Signed-off-by: Thierry Reding Signed-off-by: Dmitry Torokhov

Input: tsc2007 - add poll_period parameter to platform data

2011-05-17T16:38:49Z

This new parameter allows the polling frequency to be configured while keeping the default of once every millisecond. Signed-off-by: Thierry Reding Signed-off-by: Dmitry Torokhov

Input: tsc2007 - add poll_delay parameter to platform data

2011-05-17T16:38:43Z

Depending on the quality of the touch panel, the time for the X-, X+, Y- and Y+ inputs to settle may vary. The poll_delay parameter can be used to override the default of 1 millisecond. Cc: Dmitry Torokhov Cc: Kwangwoo Lee Signed-off-by: Thierry Reding Signed-off-by: Dmitry Torokhov

Input: tsc2007 - add max_rt parameter to platform data

2011-05-17T16:38:39Z

Finger touch events or very quick stylus events on low-quality panels can cause the tsc2007 to read bogus values. Looking at oscilloscope snapshots, this seems to be caused by the touch event disappearing during the measurements. These bogus values result in misclicks, where the X and Y values deviate from the real position. Most of these misclicks can be filtered out by setting a low enough threshold for the maximum resistance (which is loosely the inverse of the pressure) allowed to consider a set of values valid. Since this behaviour is largely dependent on the type and quality of the panel, this commit introduces the max_rt parameter. The default value is kept at MAX_12BIT.

Input: tsc2007 - debounce pressure measurement

2011-05-17T16:38:34Z

When the controller signals a pen-down event via the platform-specific GPIO, while the sample values indicate an invalid measurement, the measurement needs to be repeated. Signed-off-by: Thierry Reding Signed-off-by: Dmitry Torokhov

Input: atmel_tsadcc - correct call to input_free_device

2011-05-15T06:42:41Z

This error handling code can be reached before ts_dev->input is initialized, so it is safer to always use the original name, input_dev. Signed-off-by: Julia Lawall Signed-off-by: Dmitry Torokhov

Input: ads7846 - fix gpio_pendown configuration

2011-05-12T15:28:57Z

The pendown gpio was requested but not configured for input. Configure it for input. Signed-off-by: Igor Grinberg Signed-off-by: Dmitry Torokhov

Input: ads7846 - add possibility to use external vref on ads7846

2011-05-12T15:28:56Z

Just set vref_mv in your platform config to use external vref. Otherwise the internal one is used. Signed-off-by: Alexander Stein Signed-off-by: Dmitry Torokhov

Input: ads7846 - remove unused variable from struct ads7845_ser_req
