5 - reg: Should contain ADC registers location and length.
6 - interrupts: Should contain the IRQ line for the ADC.
7 - clocks: phandle to device clock.
8 - clock-names: Must be "adc_clk".
9 - vref-supply: Supply used as reference for conversions.
10 - vddana-supply: Supply for the adc device.
11 - atmel,min-sample-rate-hz: Minimum sampling rate, it depends on SoC.
