-* Berlin Analog to Digital Converter (ADC)
-
-The Berlin ADC has 8 channels, with one connected to a temperature sensor.
-It is part of the system controller register set. The ADC node should be a
-sub-node of the system controller node.
-
-Required properties:
-- compatible: must be "marvell,berlin2-adc"
-- interrupts: the interrupts for the ADC and the temperature sensor
-- interrupt-names: should be "adc" and "tsen"
-
-Example:
-
-adc: adc {
-	compatible = "marvell,berlin2-adc";
-	interrupt-parent = <&sic>;
-	interrupts = <12>, <14>;
-	interrupt-names = "adc", "tsen";
-};
