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.

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.

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.

2012-02-03Input: evdev - Add ioctl to block suspend while event queue is not empty.Arve Hjønnevåg
Add an ioctl, EVIOCSSUSPENDBLOCK, to enable a wakelock that will block suspend while the event queue is not empty. 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. This can prevent suspend if sensor with a high data rate is active, even when that sensor is not capable of waking the device once it is suspended.

Synaptics touchpads on several Dell laptops, particularly Vostro V13 systems, may not respond properly to PS/2 commands and queries immediately after resuming from suspend to RAM. This leads to unresponsive touchpad after suspend/resume cycle. Adding a 1-second delay after resetting the device allows touchpad to finish initializing (calibrating?) and start reacting properly.
