[PATCH v2 0/3] Allow to tune sampling time on STM32 ADC

STM32 ADC allows each channel to be sampled with a different sampling time. This series fixes common clock rate and adds optional device tree property, so minimum sampling time can be tuned. This is done via device tree as it's tightly coupled with hardware (analog source). --- Changes in v2: -
