NPCX7 includes a 10-bit resolution Analog-to-Digital Converter (ADC). Up to 10 voltage inputs can be measured and a internal voltage reference (VREF), 2.816V (typical) is used for measurement. It can be triggered automatically in Autoscan mode. Each input channel is assigned a separate result register, which is updated at the end of the conversion. The CL also includes: — Add npcx adc device tree declarations. — Zephyr adc api implementation. — Add adc definitions of npcx7 in tests/drivers/adc/adc_api/src/test_adc.c for supporting test suites.
