36       One or more interrupts for ADC block, depending on part used:
37         - stm32f4 and stm32h7 share a common ADC interrupt line.
38         - stm32mp1 has two separate interrupt lines, one for each ADC within
39           ADC block.
46         - "adc" clock: for the analog circuitry, common to all ADCs.
