+Amlogic Meson8 and Meson8b "analog top" registers:
+--------------------------------------------------
+
+The analog top registers contain information about the so-called
+"metal revision" (which encodes the "minor version") of the SoC.
+
+Required properties:
+- reg: the register range of the analog top registers
+- compatible: depending on the SoC this should be one of:
+		- "amlogic,meson8-analog-top"
+		- "amlogic,meson8b-analog-top"
+		along with "syscon"
+
+
+Example:
+
+	analog_top: analog-top@81a8 {
+		compatible = "amlogic,meson8-analog-top", "syscon";
+		reg = <0x81a8 0x14>;
+	};
