+Freescale LS1021A Platform Device Tree Bindings
+------------------------------------------------

+Freescale LS1021A SoC-specific Device Tree Bindings
+-------------------------------------------
+
+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 be "fsl,ls1021a-scfg"
+  - 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>;
+       };
+
+Freescale DCFG
+  DCFG is the device configuration unit, that provides general purpose
+configuration and status for the device. Such as setting the secondary
+core start address and release the secondary core from holdoff and startup.
+  Required properties:
+  - compatible: should be "fsl,ls1021a-dcfg"
+  - reg : should contain base address and length of DCFG memory-mapped registers
+
+Example:
+       dcfg: dcfg@1ee0000 {
+               compatible = "fsl,ls1021a-dcfg";
+               reg = <0x0 0x1ee0000 0x0 0x10000>;
+       };
