12description:
13  The ADC on iMX93 is a 8-channel 12-bit 1MS/s ADC with 4 channels
14  connected to pins. it support normal and inject mode, include
15  One-Shot and Scan (continuous) conversions. Programmable DMA
16  enables for each channel  Also this ADC contain alternate analog
17  watchdog thresholds, select threshold through input ports. And
18  also has Self-test logic and Software-initiated calibration.
