-Altera SOCFPGA SDRAM Error Detection & Correction [EDAC]
-The EDAC accesses a range of registers in the SDRAM controller.
-
-Required properties:
-- compatible : should contain "altr,sdram-edac" or "altr,sdram-edac-a10"
-- altr,sdr-syscon : phandle of the sdr module
-- interrupts : Should contain the SDRAM ECC IRQ in the
-	appropriate format for the IRQ controller.
-
-Example:
-	sdramedac {
-		compatible = "altr,sdram-edac";
-		altr,sdr-syscon = <&sdr>;
-		interrupts = <0 39 4>;
-	};
