All instances of STM32G4 should have ADC12_COMMON at address 0x50000300 in addition to ADC345_COMMON at address 0x50000700. Currently stm32-metapac provides ADC_COMMON for ADC1/2 and does not map any of the common registers for ADC3/4/5.
It's not clear to me how to fix this the right way. I can add ADC345_COMMON to data/extra/family/STM32G4.yaml, no difficulty there, but now I can't figure out how to rename the existing ADC_COMMON to ADC12_COMMON.
