Mainline synaptics touchscreen driver
Tim Bird, Sony Mobile


The synaptics touchscreen is used in many embedded project, particularly phones and tablets. However, it does not have a driver in mainline. This project would consist of mainlining it (submitting the driver and responding to community requests for enhancements.)

The driver has been submitted a number of times previously, so code is available, and many former issues have been addressed. This work was submitted in late 2012 by Christoper Heiny (a developer at Synaptics). Possibly, Synaptics engineers could assist with this effort.

Because there was not much resistance on the last submission attempt, it is possible this just fell through the cracks, and just needs a slight push to get it upstream. Or, there might be bigger issues.

It appears that the code was been accepted into Dmitry Korokhov's tree, but not progressed past that point, as of Jan 2013. Part of this project would be investigating why the code stalled, and resolving any outstanding issues to Dmitry's satisfaction.

Related work


It is notoriously difficult to estimate the time it takes to mainline something. Given the comments on the most recent submittal, however, this driver looks like it is pretty close. I would estimate 4 person-weeks.
