+Altera SOCFPGA SDRAM Error Detection & Correction [EDAC]
+
+Required properties:
+- compatible : should contain "altr,sdram-edac";
+- reg : should contain the ECC register range in sdram
+        controller (address and length).
+- interrupts : Should contain the SDRAM ECC IRQ in the
+	appropriate format for the IRQ controller.
+
+Example:
+	sdramedac@0 {
+		compatible = "altr,sdram-edac";
+		reg = <0xffc2502C 0x28>;
+		interrupts = <0 39 4>;
+	};
