+         This enables driver for STMicroelectronics STM32 analog-to-digital
+         converter (ADC).
+         A STM32 ADC block can be composed of several individual ADCs.
+         Each has its own private registers, but shares some resources:
+         - clock selection and prescaler
+         - voltage reference
+         - common registers area.
+         STM32 ADC driver is composed of:
+         - core driver to deal with common resources
+         - child driver to deal with individual ADC resources (declare ADC
+         device and associated channels, start/stop conversions)
