+* APM X-Gene SoC EDAC node
+
+EDAC node is defined to describe on-chip error detection and correction.
+The follow error types are supported:
+
+  memory controller	- Memory controller
+  PMD (L1/L2)		- Processor module unit (PMD) L1/L2 cache
+
+The following section describes the EDAC DT node binding.
+
+Required properties:
+- compatible		: Shall be "apm,xgene-edac".
+- regmap-csw		: Regmap of the CPU switch fabric (CSW) resource.
+- regmap-mcba		: Regmap of the MCB-A (memory bridge) resource.
+- regmap-mcbb		: Regmap of the MCB-B (memory bridge) resource.
+- regmap-efuse		: Regmap of the PMD efuse resource.
+- reg			: First resource shall be the CPU bus (PCP) resource.
+- interrupts            : Interrupt-specifier for MCU, PMD, L3, or SoC error
+			  IRQ(s).
+
+Required properties for memory controller subnode:
+- compatible		: Shall be "apm,xgene-edac-mc".
+- reg			: First resource shall be the memory controller unit
+                          (MCU) resource.
+- memory-controller	: Instance number of the memory controller.
+
+Required properties for PMD subnode:
+- compatible		: Shall be "apm,xgene-edac-pmd" or
+                          "apm,xgene-edac-pmd-v2".
+- reg			: First resource shall be the PMD resource.
+- pmd-controller	: Instance number of the PMD controller.
