+* ARM DMC-520 EDAC node
+
+Required properties:
+- compatible  : "brcm,dmc-520", "arm,dmc-520".
+- reg   : Address range of the DMC-520 registers.
+- interrupts  : DMC-520 interrupt numbers. The example below specifies
+     two interrupt lines for dram_ecc_errc_int and
+     dram_ecc_errd_int.
+- interrupt-names : This is an array of names corresponding to the interrupt
+     line numbers. The valid interrupt names are the followings:
+     ram_ecc_errc, ram_ecc_errd, dram_ecc_errc, dram_ecc_errd,
+     failed_access, failed_prog, link_err, temperature_event,
+     arch_fsm, phy_request
+
+Example:
+
+dmc0: dmc@200000 {
+ compatible = "brcm,dmc-520", "arm,dmc-520";
+ reg = <0x200000 0x80000>;
+ interrupts = <0x0 0x349 0x4>, <0x0 0x34B 0x4>;
+ interrupt-names = "dram_ecc_errc", "dram_ecc_errd";
+};
