+Analog signal amplifier reset
+-----------------------------
+
+Required properties:
+- compatible: should be one of the following:
+    "socionext,uniphier-ld11-adamv-reset" - for LD11 SoC
+    "socionext,uniphier-ld20-adamv-reset" - for LD20 SoC
+- #reset-cells: should be 1.
+
+Example:
+
+       adamv@57920000 {
+               compatible = "socionext,uniphier-ld11-adamv",
+                            "simple-mfd", "syscon";

+                       #reset-cells = <1>;
