For STM32 family, DAC register mappings are defined in arch/arm/src/stm32/hardware/stm32_dac.h.
In STM32Gxxxxx parts, the DAC has additional features and registers not in STM32Fxxxxx and STM32Lxxxxx parts. I propose to handle this as follows: * Rename stm32_dac.h to stm32fxxxxx_dac.h * Create a new file, stm32gxxxxx_dac.h for parts with the newer DAC * stm32_dac.h conditionally includes either stm32fxxxxx_dac.h or stm32gxxxxx_dac.h as needed Thoughts?
