2011-03-16Input: tsc2005 - use spi_get/set_drvdata()Dmitry Torokhov
Instead of peeking into underlying device and using dev_get/set_drvdata(), let's use SPI layer's implementation to access driver-private data (which may be different from driver-core private data). Tested-by: Aaro Koskinen <aaro.koskinen@nokia.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2011-02-25Input: atmel_mxt_ts - remove matrix size checkIiro Valkonen
The mxt_check_matrix_size() is currently setting the CTE mode to match xline/yline information that is in the platform data, but it does not take into account for example the fact that we could have a key array in use too (key array would use some x/y lines as well). It would be better to simply rely on the configuration data, and make sure that the CTE mode set in there matches the touch object (touchscreen, key array, proximity) configuration (which are set in the config data too).

2011-01-31Input: wacom_w8001 - report resolution to userlandPing Cheng
Serial devices send both pen and touch data through the same logical port. Since we scaled touch to pen maximum, we use pen resolution for touch as well here. This is under the assumption that pen and touch share the same physical surface. In the case when a small physical dimensional difference occurs between pen and touch, we assume the tolerance for touch point precision is higher than pen and the difference is within touch point tolerance. A per-MT tool based resolution mechanism should be introduced if the above assumption does not hold true for the pen and touch devices any more.

Some of the WM831x series of PMICs from Wolfson Microelectronics include a resistive touchscreen controller. Implement support for these controllers within the input API. Platform data is supported to allow configuration of system parameters such as selection between four and five wire touchscreens and for specification of optional direct to CPU IRQs for sample availability and for pen down. Use of this feature for at least the data IRQ is strongly recommended. Thanks to Julien Boibessot for extensive testing and detailed feedback.

2011-01-20kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

2010-12-16input: mt: Move tracking and pointer emulation to input-mtHenrik Rydberg
The drivers using the type B protocol all report tracking information the same way. The contact id is semantically equivalent to ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates the driver. The situation can be improved upon by providing a common pointer emulation code, thereby removing the need for the tracking id in the driver.
