+* Freescale on-board CPLD
+
+Some Freescale boards like T1040RDB have an on board CPLD connected.
+
+Required properties:
+- compatible: Should be a board-specific string like "fsl,<board>-cpld"
+  Example:
+       "fsl,t1040rdb-cpld", "fsl,t1042rdb-cpld", "fsl,t1042rdb_pi-cpld"
+- reg: should describe CPLD registers
+
+Example:
+       cpld@3,0 {
+               compatible = "fsl,t1040rdb-cpld";
+               reg = <3 0 0x300>;
