This patch adds bindings for QIXIS FPGA controller found on FSL boards.
Some Freescale boards like LS2080AQDS/LS2080ARDB have an on-board FPGA/CPLD
connected to the IFC controller. The bindings specified in this patch
cater to those on-board FPGA/CPLD controllers.

+Freescale Reference Board Bindings
+----------------------------------
+
+This document describes device tree bindings for various devices that
+exist on some Freescale reference boards.
+
+* Freescale on-board FPGA connected to IFC controller
+
+Some Freescale boards like LS2080AQDS/LS2080ARDB have an on-board FPGA/CPLD
+connected to the IFC controller.
+
+Required properties:
+- compatible: Should be a board-specific string followed by a string
+ indicating the type of FPGA. Example:
+ "fsl,ls2080a-qds-qixis", "fsl,fpga-qixis"
+ "fsl,ls2080a-rdb-qixis", "fsl,fpga-qixis"
+- reg: The register set for the device
+
+Example:
+ &ifc {
+ status = "okay";
+ #address-cells = <2>;
+ #size-cells <1>;
+ ranges = <0x3 0x0 0x5 0x20000000 0x00010000>;
+
+ cpld at 3,0 {
+ compatible = "fsl,ls2080a-qds-qixis", "fsl,fpga-qixis";
+ reg = <0x3 0 0x10000>;
+ };
+ };
