Subject: [RFC PATCH 0/3] iio: adc: Add support for TI ADS1120 ADC

This RFC patch series adds support for the Texas Instruments ADS1120,
a precision 16-bit delta-sigma ADC with SPI interface.

The driver provides:
- 4 single-ended voltage input channels
- Programmable gain amplifier (1 to 128)
- Configurable data rates (20 to 1000 SPS)
- Single-shot conversion mode

I'm looking for feedback on:
1. The implementation approach for single-shot conversions
2. Any other suggestions for improvement

Datasheet: https://www.ti.com/lit/gpn/ads1120
