The thing is that drivers/input/touchscreen/tsc2102_ts.c is selectable
only if driver/spi/tsc2102.c is enabled, likewise with tsc210x* and
other multi-function chips drivers. So, if you need audio you will
need to select a tsc2102_ts.c (or whatever H2 uses), but hopefully
soon this will change and tsc2102* will be dropped.

I think it was decided that drivers/input/touchscreen/omap/* was going
to be slowly removed. The code there is very platform dependent, but
it does have an advantage of being very simple and fast as is usual
for platform specific code.
