The adc v2 periph has the same register map, but comes in two flavours, one supporting injected channels, more watchdogs, per channel sampling times and so on, and one "simple" version. Pull up the f3 and f0 portions into the appropriate files, after comparing with L0 and L4 reference manuals, even if those are not fully landed yet.
