+* 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>;
+ };
