+* Amazon's Annapurna Labs L2 EDAC
+
+Amazon's Annapurna Labs SoCs supports L2 single bit correction and
+two bits detection capability based on ARM implementation.
+
+Required properties:
+- compatible:
+	should be "amazon,al-l2-edac".
+- l2-cache:
+	Phandle to L2 cache handler.
+	This property is used to compare with the CPU node property
+	'next-level-cache' to create cpu-mask with all CPUs that
+	share same L2 cache.
+
+Example:
+
+	al_l2_edac {
+		compatible = "amazon,al-l2-edac";
+		l2-cache = <&cluster0_l2>;
+	};
