OMAP tsc210x touchscreens?

OMAP tsc210x touchscreens?

[Dirk Behme]

Because of [1] I looked into drivers/input/touchscreen/omap/ts_hx.c 
what need to be done there. And, mmh, looks like

drivers/input/touchscreen/omap

can/should be completely removed? I couldn't find any Kconfig using 
TOUCHSCREEN_OMAP, so touchscreen/omap will never compile?

Instead, touchscreen/tsc210x_ts.c should be used? tsc2102_ts.c is 
outdated and replaced by tsc210x_ts.c now as well?

Regards

Dirk

Yes, kindof, the tsc210x* files were supposed to replace tsc2101* and
tsc2102* but tsc210x completely doesn't support audio yet, and there's
probably more work to be done on it (not meaning that the tsc2101 or
tsc2102 drivers in drivers/spi/ are more complete, except audio).

Anything in touchscreen/* should be completely independent from audio? 
In touchscreen/* tsc210x* should be sufficent then and tsc2102* & 
omap/* in *input/touchscreen* are redundant?

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.
