On STM32MP13x, each ADC peripheral has a single ADC block. These ADC peripherals, ADC1 and ADC2, are fully independent. Main characteristics of STM32MP13x ADC: - One interrupt line per ADC - 6 to 12 bits resolution - 19 channels ADC2 instance supports two extra internal channels VDDCPU and VDDQ_DDR. Add "vddcpu" and "vddq_ddr" internal channels names to the reserved labels list.
