Is anyone currently working on that topic?

We need the DAC for STM32L0 and STM32G4 series MCUs. Instead of implementing it only for our project, I can start with the generic DAC driver API and STM32 implementation.

The API would be derived from the ADC. But it is more simple, as a DAC doesn't need async calls and doesn't have gain settings etc.

Is it possible to skip syscalls / userspace option in the first step?

Just assumed nobody was working on that topic at the moment as it is quite an old one. So tried my best to implement it myself, see above mentioned PR.
