2014-02-04input: touchscreen: fusion: platform independent GPIO descriptionStefan Agner
Use platform independent description for requested GPIOs.
2014-01-29input: touchscreen: fusion: fix error handlingStefan Agner
Fix chip reset by sleeping long enought after reset. Do proper error handling (free GPIO on failure). Use dev_* for message logging to get similar messages for all fusion driver related errors and warnings.
2014-01-29input: touchscreen: fusion: use new I2C PM functionsStefan Agner
To avoid warnings use the new I2C power management function for suspend and resume.
2014-01-29input: touchscreen: added platform data for Fusion touchscreenStefan Agner
Added platform data struct to define interrupt and reset GPIO. This allows to initialize the touchscreen controller inside the driver rather then in each platform and use the driver as a module.
2014-01-29input: touchscreen: fix race condition in Fusion driverStefan Agner
When the next interrupt request apeares between the confirmation of the previous (a write via I2C, fusion_F0710A_write_complete) and the reenable of the GPIO interrupt, the driver hangs and no more touch inputs are reported. This patch moves the confirmation after the reenabling of the GPIO interrupt.
2014-01-29input: touchscreen: add ABS_X/ABS_Y axis for Fusion touchscreenStefan Agner
Recent evdev X-Server input driver implementation complain when only multitouch axes have been reported ("found only multitouch-axes. That shouldn't happen."). Therefor also report the primary touch detection with default axis.
2013-12-09mfd: stmpe: add ADC block resourcesStefan Agner
In order to use the auxiliar ADC inputs of STMPE811 devices we need to add resources for the ADC block. Also move the ADC macros from the touchscreen driver to the general header file. We will need them for the ADC driver in future.
2013-04-02input: touchscreen: android ics fusion_F0710A driver variantMarcel Ziswiler
For Android use ICS variant of Fusion 7 and 10 multi-touch driver (See Fusion 7 and 10 drivers for Linux.pdf and Linux Drivers Fusion 10.zip). Tested to be working both with Android 4.0.4 for Colibri T20 as well as Android 4.2.1 for Colibri T30.
2013-03-24input: touchscreen: wm97xx-core: android idc parser hackMarcel Ziswiler
The Android idc parser seems to have an issue with spaces in names: D/EventHub( 159): No input device configuration file found for device 'wm97xx touchscreen'. Rename the driver in order for the idc parser to recognise idc file /system/usr/idc/wm97xx-ts.idc being a simple copy of the qwerty.idc one.
2013-03-24input: touchscreen: wm97xx-core: android orientation hackMarcel Ziswiler
Rotate touch for now due to missing resistive touch calibration integration. This makes our 5.7 inch EDT ET057090DHU panel usable.
2013-02-21input: touchscreen: stmpe-ts: android orientation hackMarcel Ziswiler
Rotate touch for now due to missing resistive touch calibration integration. This makes our 7 inch EDT ET070080DH6 panel usable.
2013-02-12input: touchscreen: add Fusion 7 and 10 multi-touch driverMarcel Ziswiler
This patch adds the multi-touch input driver for the TouchRevolution Fusion 7 and 10 panels (See Fusion 7 and 10 drivers for Linux.pdf and Linux Drivers Fusion 10.zip).

2012-11-02colibri_t20: wm97xx-battery: android: analog input ugly hackMarcel Ziswiler
Android immediately shuts down due to too low voltage reading from wm97xx-battery driver on our analog input pins if nothing is connected. Making our hack not Android dependant means driver still fails loading on Android therefore resolving above issue for now.
2012-10-18colibri_t20: analog input ugly hackMarcel Ziswiler
While the ADC platform data passing worked just fine in kernel 2.6.36.2 this currently fails. Therefore introduce an ugly hack to explicitly get said data via a board level call back.
2012-10-10input: stmpe-ts: fix touch release detectionMarcel Ziswiler
Previous HZ / 50 calculation allowed for a touch sampling time of 20 ms which is not sufficient if either the touch detect delay or the settling time is longer than 500 us.
