Below properties are supported by only by ti_am3335x_adc driver and not
ti_am335x_tsc driver. As author of this patch pointed out in another
reply, there is no need to change step-opendelay for tsc. AFAIK, I don't
see a use case where these values needs to be tweaked for tsc channels,
therefore it does not make sense to be DT properties.

Its totally upto board dts files to allocate channels for tsc and adc.
So, how could these be added to dtsi files?
