+Freescale SCFG
+
+SCFG is the supplemental configuration unit, that provides SoC specific
+configuration and status registers for the chip. Such as getting PEX port
+status.
+
+Required properties:
+  - compatible: Should contain a chip-specific compatible string,
+	Chip-specific strings are of the form "fsl,<chip>-scfg",
+	The following <chip>s are known to be supported:
+	ls1012a, ls1021a, ls1043a, ls1046a, ls2080a.
+
+  - reg: should contain base address and length of SCFG memory-mapped registers
+
+Example:
+	scfg: scfg@1570000 {
+		compatible = "fsl,ls1021a-scfg";
+		reg = <0x0 0x1570000 0x0 0x10000>;
+	};
