help
Enable the driver for Texas Instruments ADS1220 24-bit, 4-channel,
low-power Delta-Sigma ADC with integrated PGA, VREF, SPI interface,
and two IDACs.

The ADS1220 is a precision ADC designed for high-resolution measurements
in sensor applications such as temperature, pressure, and strain sensing.

Features supported by this driver:
- 24-bit resolution with up to 2000 samples per second
- 4 multiplexed input channels (single-ended and differential)
- Programmable gain amplifier (1 to 128)
- Internal 2.048V reference or external reference
- Two matched excitation current sources (IDACs)
- Supply monitoring capabilities
- 50/60 Hz rejection filters
- Low power operation modes

help
Initialization priority for the ADS1220 ADC driver.
Must be higher than SPI bus initialization priority and lower
than application initialization priority.

config ADC_ADS1220_WAIT_FOR_COMPLETION_TIMEOUT_MS
int "Timeout for wait for completion of a read in ms"
default 250
help
This is the wait time in ms until a read is completed.
