/* There are 2 main types of ADC IP cores among STM32 chips:
 *   1. STM32 ADC IPv1:
 *     a) basic version for F1 and F37x
 *     b) extended version for F2, F4, F7, L1:
 *   2. STM32 ADC IPv2:
 *     a) basic version for F0 and L0
 *     b) extended version for F3 (without F37x), G4, H7, L4, L4+
 *
 *   We also distinguish these variants:
 *   1. The modified STM32 ADC IPv1 core for the L1 family, which differs
 *      too much to keep it in the same file as ADC IPv1.
 *   2. The modified STM32 ADC IPv2 core for the G4 family, which differs
 *      too much to keep it in the same file as ADC IPv2.
