TSC2004 touch driver
I'm trying to incorporate a TSC2004 touch driver for my omap3430 board, and before I go off and reinvent the wheel, fiugred I'd ask. Google doesn't come up with anything for a driver on tsc2004.
Thanks in advance!

Peter,
We used the TSC2046, which is a "next generation ADS7846" chip. We just used the ads7846 driver and it worked fine. The TSC2004 datasheet doesn't make the same compatibility claim however. The ads7846 driver is a place to start.
The TSC2004 is I2C, wheras the ADS7846 is SPI. I've found a TSC2003 driver written by Bill Gatliff for 2.4, but was wondering if anyone had a better starting point.
Also, any idea where I can find a "snap" (as in source) of the kernel work-in-progress, or is it all in the git trees?
