The tsc2005 still needs devicetree conversion, so it is at least 2 patches away
from where I can use it.

I have missed the window for my companies OE release so I doubt I will
have time to code

I am in the process of routing a AM335x SoM which obsoletes this AM3517 one
so my resources will be elsewhere.
