+Designated hotplug memory
+-------------------------
+
+This binding describes a region of hotplug memory which is not present at boot,
+allowing its eventual NUMA associativity to be prespecified.
+
+Required properties:
+
+- compatible
+	"ibm,hotplug-aperture"
+
+- reg
+	base address and size of the region (standard definition)
+
+- ibm,associativity
+	NUMA associativity (standard definition)
+
+Example:
+
+A 2 GiB aperture at 0x100000000, to be part of nid 3 when hotplugged:
+
+	hotplug-memory@100000000 {
+		compatible = "ibm,hotplug-aperture";
+		reg = <0x0 0x100000000 0x0 0x80000000>;
+		ibm,associativity = <0x4 0x0 0x0 0x0 0x3>;
+	};
