    1 Integrated Flash Controller
    2 
    3 Properties:
    4 - name : Should be ifc
    5 - compatible : should contain "fsl,ifc". The version of the integrated
    6                flash controller can be found in the IFC_REV register at
    7                offset zero.
    8 
    9 - #address-cells : Should be either two or three.  The first cell is the
   10                    chipselect number, and the remaining cells are the
   11                    offset into the chipselect.
   12 - #size-cells : Either one or two, depending on how large each chipselect
   13                 can be.
   14 - reg : Offset and length of the register set for the device
   15 - interrupts: IFC may have one or two interrupts.  If two interrupt
   16               specifiers are present, the first is the "common"
   17               interrupt (CM_EVTER_STAT), and the second is the NAND
   18               interrupt (NAND_EVTER_STAT).  If there is only one,
   19               that interrupt reports both types of event.
   20 
   21 - little-endian : If this property is absent, the big-endian mode will
   22                   be in use as default for registers.
   23 
   24 - ranges : Each range corresponds to a single chipselect, and covers
   25            the entire access window as configured.
   26 
   27 Child device nodes describe the devices connected to IFC such as NOR (e.g.
   28 cfi-flash) and NAND (fsl,ifc-nand). There might be board specific devices
   29 like FPGAs, CPLDs, etc.
