Subject[PATCH v2 0/3] mainline ti tsc2046 adc driver
Date
changes v2:
- rework and extend DT binding properties
- remove touchscreen related code from the IIO ADC driver
- make trigger be active longer then IRQ is requesting. This is needed
to get "inactive" samples
- make oversampling and settle time configurable

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 ;) )

Oleksij Rempel (3):
dt-bindings:iio:adc: add generic settling-time-us and average-samples
channel properties
dt-bindings:iio:adc: add documentation for TI TSC2046 controller
iio: adc: add ADC driver for the TI TSC2046 controller
