   13   NXP's integrated flash controller (IFC) is an advanced version of the
   14   enhanced local bus controller which includes similar programming and signal
   15   interfaces with an extended feature set. The IFC provides access to multiple
   16   external memory types, such as NAND flash (SLC and MLC), NOR flash, EPROM,
   17   SRAM and other memories where address and data are shared on a bus.

   28     description: |
   29       Should be either two or three.  The first cell is the chipselect
   30       number, and the remaining cells are the offset into the chipselect.
   31 
   32   "#size-cells":
   33     enum: [1, 2]
   34     description: |
   35       Either one or two, depending on how large each chipselect can be.

   43     description: |
   44       IFC may have one or two interrupts.  If two interrupt specifiers are
   45       present, the first is the "common" interrupt (CM_EVTER_STAT), and the
   46       second is the NAND interrupt (NAND_EVTER_STAT).  If there is only one,
   47       that interrupt reports both types of event.
   48 
   49   little-endian:
   50     type: boolean
   51     description: |
   52       If this property is absent, the big-endian mode will be in use as default
   53       for registers.
   54 
   55   ranges:
   56     description: |
   57       Each range corresponds to a single chipselect, and covers the entire
   58       access window as configured.

   64       Child device nodes describe the devices connected to IFC such as NOR (e.g.
   65       cfi-flash) and NAND (fsl,ifc-nand). There might be board specific devices
   66       like FPGAs, CPLDs, etc.
