[PATCH v3 0/6] iio: at91: Add touch screen support in at91 adc

[Josh Wu]

This patch series introduce multiple compatible string for different ip.
So remove some adc dt parameters as it already included in driver code.

It also touch screen support for at91 adc driver.
To enable touch screen you need add the touch screen related dt properties.

v2 --> v3:
  1. move the dt parameters to driver itself.
  2. trival fix in touch driver.

v1 --> v2:
  1. use multiple compatible string for different ADC IP.
  2. drop the patch that add the adc-clock in dt since we will move to clock
     common framework.
  3. don't expose the driver configuration to dt. Such like sample period,
     pen detect debounce time and etc.
  4. add a new dt parameter: ts-pressure-threshold.
