Hi Linus, all, As you suggested during the submission of the STM32 machine support, I reworked the STM32 pinctrl driver to use the standardized pin config bindings.
The STM32 family has 16 pins per GPIO bank, and the number of bank varies depending on the model. Pins can be multiplexed either in GPIO mode, alternate function (up to 15 functions per pin) or analog (for ADC/DAC).
