Mainline synaptics touchscreen driver

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 may former issues have been resolved. 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 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.
