+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@ffc2502c {
+ compatible = "altr,sdram-edac";
+ reg = <0xffc2502c 0x28>;
+ interrupts = <0 39 4>;
