+Altera SoCFPGA ECC Manager
+This driver uses the EDAC framework to implement the SOCFPGA ECC Manager.
+The ECC Manager counts and corrects single bit errors and counts/handles
+double bit errors which are uncorrectable.
+
+Cyclone5 and Arria5 ECC Manager
+Required Properties:
+- compatible : Should be "altr,socfpga-ecc-manager"
+- #address-cells: must be 1
+- #size-cells: must be 1
+- ranges : standard definition, should translate from local addresses
+
+Subcomponents:
+
+L2 Cache ECC
+Required Properties:
+- compatible : Should be "altr,socfpga-l2-ecc"
+- reg : Address and size for ECC error interrupt clear registers.
+- interrupts : Should be single bit error interrupt, then double bit error
+ interrupt. Note the rising edge type.
+
+On Chip RAM ECC
+Required Properties:
+- compatible : Should be "altr,socfpga-ocram-ecc"
+- reg : Address and size for ECC error interrupt clear registers.
+- iram : phandle to On-Chip RAM definition.
+- interrupts : Should be single bit error interrupt, then double bit error
+ interrupt. Note the rising edge type.
+
+Example:
+
+ eccmgr: eccmgr@ffd08140 {
+ compatible = "altr,socfpga-ecc-manager";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ l2-ecc@ffd08140 {
+ compatible = "altr,socfpga-l2-ecc";
+ reg = <0xffd08140 0x4>;
+ interrupts = <0 36 1>, <0 37 1>;
+ };
+
+ ocram-ecc@ffd08144 {
+ compatible = "altr,socfpga-ocram-ecc";
+ reg = <0xffd08144 0x4>;
+ iram = <&ocram>;
+ interrupts = <0 178 1>, <0 179 1>;
+ };
+ };
+
+Arria10 SoCFPGA ECC Manager
+The Arria10 SoC ECC Manager handles the IRQs for each peripheral
+in a shared register instead of individual IRQs like the Cyclone5
+and Arria5. Therefore the device tree is different as well.
+
+Required Properties:
+- compatible : Should be "altr,socfpga-a10-ecc-manager"
+- altr,sysgr-syscon : phandle to Arria10 System Manager Block
+ containing the ECC manager registers.
+- #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:
+
+L2 Cache ECC

+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>;
