+Integrated Flash Controller
+
+Properties:
+- name : Should be ifc
+- compatible : should contain "fsl,ifc". The version of the integrated
+ flash controller can be found in the IFC_REV register at
+ offset zero.
+
+- #address-cells : Should be either two or three. The first cell is the
+ chipselect number, and the remaining cells are the
+ offset into the chipselect.
+- #size-cells : Either one or two, depending on how large each chipselect
+ can be.
+- reg : Offset and length of the register set for the device
+- interrupts: IFC may have one or two interrupts. If two interrupt
+ specifiers are present, the first is the "common"
+ interrupt (CM_EVTER_STAT), and the second is the NAND
+ interrupt (NAND_EVTER_STAT). If there is only one,
+ that interrupt reports both types of event.
+
+
+- ranges : Each range corresponds to a single chipselect, and covers
+ the entire access window as configured.
+
+Child device nodes describe the devices connected to IFC such as NOR (e.g.
+cfi-flash) and NAND (fsl,ifc-nand). There might be board specific devices
+like FPGAs, CPLDs, etc.
+
+Example:
+
+ ifc@ffe1e000 {
