  12 description:
  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.
