[PATCH 09/10] ARM: dts: at91: sama5d2: add rtc_adc_trigger node

From: Eugen Hristev <eugen.hristev@microchip.com>

Add node for the AT91 RTC ADC Trigger.
This is a child node of the RTC and uses the same register map.
Add a link in the ADC node to this new node. This represents the internal
hardware line that is connected from the ADC to the RTC device.
