+* ARM Cortex A15 L2 internal asynchronous error detection driver
+
+Support for L2 internal asynchronous error detection caused by L2 RAM
+double-bit ECC error or illegal writes to the Interrupt Controller
+memory-map region on the Cortex A15.
+
+Required properties:
+	- compatible: "arm,cortex-a15-l2-async-edac"
+	- interrupts: INTERRIRQ per CPU cluster
+
+Example:
+
+cortex-a15-l2-async-edac {
+	compatible = "arm,cortex-a15-l2-async-edac";
+	interrupts = <0 182 4>,
+		     <0 183 4>,
+		     <0 184 4>,
+		     <0 185 4>;
+};
