2015-11-02input: touchscreen: fusion: implement multitouch with slot handlingStefan Agner
According to multi-touch-protocol.txt the kernel knows two type of devices: - Type A: devices which provide anonymous contacts - Type B: devices which are capable of tracking individual contacts The Fusion touch screen is a Type B device: The Touch ID field allows to differentiate between 2 different fingers. This updates the driver to properly allocate a slot for each identified contact and use the helper functions available from the input core system. (cherry picked from commit 698d0a9bb80d94adef58122717c61f55dd61e22d)
2015-11-02input: touchscreen: fusion: use level triggered interruptStefan Agner
Use level triggered interrupt which makes sure that even we miss a rising edge (due to latencies in the kernel), the interrupt still will be handled later, and doesn't freeze the input device. (cherry picked from commit ef25b8a9f9c0ca7cc0f0f955d89d112c3e19f75b)

2014-01-29input: touchscreen: fusion: fix error handlingStefan 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.
2013-12-02colibri_t20/colibri_t30: don't register KEY_BACK for wakeupStefan Agner
The port used for KEY_BACK does not support wakeup (no wake PIN). Remove the wake flag, this prevents unbalanced irq warning messages.

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.

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.

This allows userspace code to process input events while the device appears to be asleep. The current code holds the wakelock for up 5 seconds for every input device and client.
