Updated as suggested. Refactored to follow the STM32H5 approach: - Removed all Kconfig options and custom lower-half operations. - Added `difsel` to `struct stm32_dev_s`, initialized from `BOARD_ADCx_DIFSEL` (if defined) or defaulting to `ADC_DIFSEL_DEFAULT` (`0`). - Written directly to `STM32_ADC_DIFSEL_OFFSET` in `adc_configure()`. - Implemented calibration in `adc_calibrate()` supporting single-ended (`ADCALDIF=0`) and differential (`ADCALDIF=1`) calibration based on `priv->difsel` (matching the STM32H5 pattern). - Tested and verified on physical hardware (Nucleo-G431KB) with differential channel 1 against 0V, +3.3V, and -3.3V. -- This is an automated message from the Apache Git Service.
