[PATCH v1 0/2] Input: touchscreen: Minor colibri-vf50-ts cleanups

[Francesco Dolcini]

Hi all,
This series introduce some minor cleanups on colibri-vf50-ts, allow using it
with any IIO ADC input and fix a couple of mistakes in the dt-bindings
documentation.

[PATCH v1 1/2] Input: touchscreen: colibri-vf50-ts: don't depend on VF610_ADC

[Francesco Dolcini]

From: Max Krummenacher <max.krummenacher@toradex.com>

Any IIO ADC can be used with the driver, so do not depend
on VF610_ADC.
