Subject: [PATCH v1 0/2] mainline ti tsc2046 adc driver
Date: Fri,  5 Mar 2021 14:38:11 +0100	[thread overview]
Message-ID: <20210305133813.27967-1-o.rempel@pengutronix.de> (raw)

TI TSC2046 is a touchscreen controller based on 8 channel ADC. Since most of
this ADC based touchscreen controller share same set of challenges, it
is better keep then as simple IIO ADC devices attached to a generic
resistive-adc-touch driver.

This driver can replace drivers/input/touchscreen/ads7846.c and has
following advantages over it:
- less code to maintain
- shared code paths (resistive-adc-touch, iio-hwmon, etc)
- can be used as plain IIO ADC to investigate signaling issues or test
  real capacity of the plates and attached low-pass filters
  (or use the touchscreen as a microphone if you like ;) )
