+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"
+- #address-cells: must be 1
+- #size-cells: must be 1
+- 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.
+- ranges : standard definition, should translate from local addresses
+
+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: eccmgr {
+ compatible = "altr,socfpga-s10-ecc-manager";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ interrupts = <0 15 4>, <0 95 4>;
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ ranges;
+
+ sdramedac {
+ compatible = "altr,sdram-edac-s10";
+ interrupts = <16 4>, <48 4>;
+ };
+ };
