Your "build" of libopencm3? adc v1 and adc v2 are for different versions of the ADC peripheral. You "choose" one or the other by choosing whether to use stm32f1, f4, f3, l1, l4, f0. Some of them have peripheral v1, some have periph v2. I would caution that particularly with some of the common shared files, the doxygen generated is sometimes both missing sections, and including inappropriate sections. Reading only the doxygen is quite likely to sometimes add to confusion. I'd love some work there. I have done, and will continue to do, work to try and standardize the apis for as many functions as possible, but yes, there are inconsistencies. If you're particularly looking at ADC for instance, try having a look at https://github.com/karlp/libopencm3-tests/tree/master/tests/adc-power particularly compare the f1 and f4 files there.
