TSC2004 driver

The TSC2004 driver has yet to appear in the mainline kernel. We have
been using the driver referenced here as provided by TI:

https://www.mail-archive.com/linux-omap@vger.kernel.org/msg22018.html

Are there any plans of supporting this device in the mainline kernel?

Mysteriously a device tree entry was found in the following file:
arch/arm/boot/dts/omap4-var-som-om44.dtsi

This is obviously pointing to an out of tree driver that is not easily
obtained.

Suggestions?
