+Stratix10 SoCFPGA ECC Manager
+The Stratix10 SoC ECC Manager handles the IRQs for each peripheral
+in a shared register similar to the Arria10. However, ECC requires
+access to registers that can only be read from Secure Monitor with
+SMC calls. Therefore the device tree is slightly different.
+
+Required Properties:
+- compatible : Should be "altr,socfpga-s10-ecc-manager"
+- interrupts : Should be single bit error interrupt, then double bit error
+        interrupt.
+- interrupt-controller : boolean indicator that ECC Manager is an interrupt controller
+- #interrupt-cells : must be set to 2.
+
+Subcomponents:
+
+SDRAM ECC
+Required Properties:
+- compatible : Should be "altr,sdram-edac-s10"
+- interrupts : Should be single bit error interrupt, then double bit error
+        interrupt, in this order.
+
+Example:
+
+        eccmgr {
+                compatible = "altr,socfpga-s10-ecc-manager";
+                interrupts = <0 15 4>, <0 95 4>;
+                interrupt-controller;
+                #interrupt-cells = <2>;
+
+                sdramedac {
+                        compatible = "altr,sdram-edac-s10";
+                        interrupts = <16 4>, <48 4>;
+                };
