+ Bindings for the Microchip AT91 RTC ADC Trigger.
+ The Real Time Clock block inside AT91 SoCs can be connected with a direct
+ hardware line to the ADC. This line can be raised at a specific time
+ interval in order to trigger the ADC to perform conversions.
+ Datasheet can be found here: http://ww1.microchip.com/downloads/en/devicedoc/ds60001476b.pdf
